Authors: Torba Dmitriy I. , Bochkarev Alexander V. , Ovcharenko Yuriy V. , Glazyrina Alexandra E. , Berezovskiy Yuriy S. , Metelkin Denis V.
Published: October 2021

Background. Tight sand deposits development has always been a challenging process that frequently requires application of innovative approaches. Horizontal drilling in non-uniform lithology is frequently accompanied by circulation, wellbore stability losses and other complications. Hydraulic fracturing stimulation does not always result in productivity increase, which reduces profitability of development. Due to the incomplete understanding of geological and geomechanical specifics of Achimov deposits, — formations with complex heterogenous structure, low permeability, presence of low-amplitude structural dislocations, — the controlled use of features of formation is hindered and, in turn, makes it necessary to develop an innovative strategy of their surveillance and stimulation. Aim. In purpose to optimize an existing development strategy of Achimov deposits in Vingayakhinskoe oilfield, we have developed and applied an approach involving complex cross-segment modelling. At the same time, verification of hypothesis on possibility to identify and activate naturally fractured zones. Materials and methods. To form criteria for verification of hypothesis of fracture network generation in Achimov deposits, a 1D and 3D geomechanical models have been built in view of the applied approach, along with a model of natural fractures. Development of hydraulic fracturing designs, efficiency of which has been evaluated with respect to such reservoir modeling results as predicted production rate and cumulative production, have been the next step, performed for different geological and geomechanical conditions. Thus, the principal feature of applied approach is coupling between geomechanical modeling, complex multivariant hydraulic fracturing modeling and reservoir modeling with the target to maximize production. Results. The well stimulation strategy, selected based on the results of multivariate integrated modeling, was successfully implemented as part of the pilot high-flow hydraulic fracturing operation, which led to an almost twofold increase in the initial production rates of project wells versus off set wells. Conclusions. The obtained results of the work confirm that the developed integrated modeling approach can serve as a reliable basis for optimizing the development of heterogeneous and low-permeability formations such as Achimov deposits.
Specific features of the probability petrophysical estimation of rock formations using the approaches of the concept of porous space connectedness
Authors: Belyakov Еvgeniy О.
Published: October 2021

Background. The technology of probability petrophysical estimation of parameters using layer-bylayer interpretation of well logging data is present in this paper. Specific features of the technology is to using both the vertical and horizontal processing.
Aim. The aim of the technology is the possibility of its adaptation when interpreting well logging data using the approaches of the concept of pore space connectedness, which reduce the variability of estimates of productive thicknesses of reservoirs in comparison with traditional approaches to calculating geological reserves using fixed cutoff porosity coefficient.
Materials and methods. The paper discusses the main features of modeling the uncertainties of the input parameters and ways of representing them in the form of various distributions with a description of a generalized algorithm for the probabilistic assessment of geological reserves. The distributions of the reservoir area, oil density and conversion factor, the basic version of the results of the reservoir logging data interpretation in the form of a table continuous in depth with readings from the logging methods curves in intervals homogeneous in lithology are use as input parameters when executing the algorithm. In addition, distributions reflecting variations in the uncertainties of geophysical parameters, constants of petrophysical models, boundary cutoff s for identifying reservoirs and assessing their saturation nature are used to the input of the algorithm.
Results. An algorithm for probabilistic petrophysical assessment has been developed taking into account the use of petrophysical modeling within the framework of the concept of pore space connectivity and the layer-by-layer mode of interpretation of well logging data. It is shown that additional petrotyping, which makes it possible to clarify the parameter of pore space connectivity, reduces the error of the resulting estimates, which can reduce the risk of making ineffective decisions.
Conclusions. It is show that additional petrotyping, which makes it possible to clarify the parameter of pore space connectedness, reduces the error of the resulting estimates, which can reduce the risk of making ineffective decisions.

Published: October 2021

Background. An optimal exploration strategy creates a significant share in value of project on exploration stage. The paper describes an example of solving the following tasks: determining the feasibility of additional exploration drilling; evaluating the value of drilling of one or more exploration wells; determining the optimal placement for exploration wells and drilling order. Authors presenting the modification of VoI (Value of Information) method and its application. Materials and methods. Complex probabilistic models were created summarizing main uncertainties and limitations, both geological, technical and technological. At the first stage three equiprobable geological concepts were made. For each concept probabilistic geological modelling was proceeded and then realizations corresponding to values of reserves P10, P50, and P90 were selected. Further, detailed production forecasts and economic estimates were performed. The analysis used the well pad and the corresponding area for exploration drilling as a unit of calculation. In the article the authors introduced the concept of remaining uncertainty. Application of modified VoI method allowed to form ‘dynamic’ (i.e. depending on exploration wells drilling order) range of areas for additional exploration which provide the best decrease of remaining uncertainty. An additional exploration strategy has been formed, which includes the necessary and sufficient number of wells and their drilling order. A decision tree was created depending on the success or failure of each subsequent exploration well. Results. The use of the modified VoI approach made it possible to achieve the objectives and obtain economical estimates, all of which combined to facilitate the adoption of decisions. As a result, a program for two exploration well drilling was created which would reduce the uncertainty by 90% from its initial value. Conclusions: The adopted VoI method could be applied to fields at the stage of additional exploration as well as to fields at early exploration stage to develop an exploration drilling strategy.

Abstract. This study presents the source apportionment of PM2.5 performed by positive matrix factorization (PMF) on data presented here which were collected at urban (Institute of Atmospheric Physics – IAP) and rural (Pinggu – PG) sites in Beijing as part of the Atmospheric Pollution and Human Health in a Chinese megacity (APHH-Beijing) field campaigns. The
campaigns were carried out from 9 November to 11 December 2016
and from 22 May to 24 June 2017. The PMF analysis included both organic and inorganic species, and a seven-factor output provided the most reasonable solution for the PM2.5 source apportionment. These factors are
interpreted as traffic emissions, biomass burning, road dust, soil dust, coal combustion, oil combustion, and secondary inorganics. Major contributors
to PM2.5 mass were secondary inorganics (IAP: 22 %; PG: 24 %),
biomass burning (IAP: 36 %; PG: 30 %), and coal combustion (IAP: 20 %;
PG: 21 %) sources during the winter period at both sites. Secondary
inorganics (48 %), road dust (20 %), and coal combustion (17 %) showed the highest contribution during summer at PG, while PM2.5 particles
were mainly composed of soil dust (35 %) and secondary inorganics (40 %)
at IAP. Despite this, factors that were resolved based on metal signatures
were not fully resolved and indicate a mixing of two or more sources. PMF
results were also compared with sources resolved from another receptor model
(i.e. chemical mass balance – CMB) and PMF performed on other measurements (i.e. online and offline aerosol mass spectrometry, AMS) and showed good agreement for some but not all sources. The biomass burning factor in PMF may contain aged aerosols
as a good correlation was observed between biomass burning and oxygenated
fractions (r2= 0.6–0.7) from AMS. The PMF failed to resolve some sources identified by the CMB and AMS and appears to overestimate the dust sources. A comparison with earlier PMF source apportionment studies from the
Beijing area highlights the very divergent findings from application of this
method.
Geochemical and reactive transport modelling in R with the RedModRphree package
Authors: De Lucia Marco , Kühn Michael
Published: October 2021

Abstract. Advances in computing and experimental capabilities in the research
of water-rock-interactions require geoscientists to routinely
combine laboratory data and models to produce new knowledge. Data
science is hence a more and more pervasive instrument for
geochemists, which in turn demands flexible and easy to learn
software adaptable to their specific needs. The GNU R language and
programming environment has established itself as de facto standard
language for statistics and machine learning, enjoying increasing
diffusion in many applied scientific fields such as bioinformatics,
chemometrics and ecological modelling. The availability of excellent
third party extensions as well as its advanced graphical and
numerical capabilities make R an ideal platform for comprehensive
geochemical data analysis, experiment evaluation and modelling. We introduce the open source RedModRphree extension
package, which leverages the R interface to the established
PHREEQC geochemical simulator. The aim of
RedModRphree is to provide the user with an easy-to-use,
high-level interface to program algorithms involving geochemical
models: parameter calibration, error and sensitivity analysis,
thermodynamical database manipulation, up to CPU-intensive parallel
coupled reactive transport models. Among the out-of-the-box features
included in RedModRphree, we highlight the computation and
visualization of Pourbaix (Eh-pH) diagrams using full speciation as
computed by PHREEQC and the implementation of 1D advective
reactive transport supporting the use of surrogate models replacing
expensive equation-based calculations.

Abstract. Satellite measurements enable quantification of atmospheric temperature, humidity, and trace gas vertical profiles. The majority of current instruments operate on polar orbiting satellites and either in the thermal/mid-wave or in the shortwave infrared spectral regions. We present a new multispectral instrument concept for improved measurements from geostationary orbit (GEO) with sensitivity to the boundary layer. The JPL GEO-IR sounder, which is an imaging Fourier Transform Spectrometer, uses a wide spectral range (1–15.4 μm), encompassing both reflected solar and thermal emission bands to improve sensitivity to the lower troposphere and boundary layer. We perform retrieval simulations for both clean and polluted scenarios that also encompass different temperature and humidity profiles. The results illustrate the benefits of combining shortwave and thermal infrared measurements. In particular, the former adds information in the boundary layer, while the latter helps to separate near-surface and mid-tropospheric variability. The performance of the JPL GEO-IR sounder is similar to or better than currently operational instruments. The proposed concept is expected to improve weather forecasting, severe storm tracking and forecasting, and also benefit local and global air quality and climate research.
Preferential pathways for fluid and solutes in heterogeneous groundwater systems: self-organization, entropy, work
Authors: Zehe Erwin , Loritz Ralf , Edery Yaniv , Berkowitz Brian
Published: October 2021

Abstract. Patterns of distinct preferential pathways for fluid flow and solute
transport are ubiquitous in heterogeneous, saturated and partially saturated
porous media. Yet, the underlying reasons for their emergence, and their
characterization and quantification, remain enigmatic. Here we analyze
simulations of steady-state fluid flow and solute transport in
two-dimensional, heterogeneous saturated porous media with a relatively
short correlation length. We demonstrate that the downstream concentration
of solutes in preferential pathways implies a downstream declining entropy
in the transverse distribution of solute transport pathways. This reflects
the associated formation and downstream steepening of a concentration
gradient transversal to the main flow direction. With an increasing variance
of the hydraulic conductivity field, stronger transversal concentration
gradients emerge, which is reflected in an even smaller entropy of the
transversal distribution of transport pathways. By defining
“self-organization” through a reduction in entropy (compared to its
maximum), our findings suggest that a higher variance and thus randomness of
the hydraulic conductivity coincides with stronger macroscale
self-organization of transport pathways. Simulations at lower driving head
differences revealed an even stronger self-organization with increasing
variance. While these findings appear at first sight striking, they can be
explained by recognizing that emergence of spatial self-organization
requires, in light of the second law of thermodynamics, that work be
performed to establish transversal concentration gradients. The emergence of
steeper concentration gradients requires that even more work be performed,
with an even higher energy input into an open system. Consistently, we find
that the energy input necessary to sustain steady-state fluid flow and
tracer transport grows with the variance of the hydraulic conductivity field
as well. Solute particles prefer to move through pathways of very high power
in the transversal flow component, and these pathways emerge in the vicinity
of bottlenecks of low hydraulic conductivity. This is because power depends
on the squared spatial head gradient, which is in these simulations largest
in regions of low hydraulic conductivity.
How is Baseflow Index (BFI) impacted by water resource management practices?
Authors: Bloomfield John P. , Gong Mengyi , Marchant Benjamin P. , Coxon Gemma , Addor Nans
Published: October 2021

Abstract. Water resource management (WRM) practices, such as groundwater and surface water abstractions and effluent discharges, may impact baseflow. Here the CAMELS-GB large-sample hydrology dataset is used to assess the impacts of such practices on Baseflow Index (BFI) using statistical models of 429 catchments from Great Britain. Two complementary modelling schemes, multiple linear regression (LR) and machine learning (random forests, RF), are used to investigate the relationship between BFI and two sets of covariates (natural covariates only and a combined set of natural and WRM covariates). The LR and RF models show good agreement between explanatory covariates. In all models, the extent of fractured aquifers, clay soils, non-aquifers, and crop cover in catchments, catchment topography, and aridity are significant or important natural covariates in explaining BFI. When WRM terms are included, groundwater abstraction is significant or the most important WRM covariate in both modelling schemes, and effluent discharge to rivers is also identified as significant or influential, although natural covariates still provide the main explanatory power of the models. Surface water abstraction is a significant covariate in the LR model but of only minor importance in the RF model. Reservoir storage
covariates are not significant or are unimportant in both the LR and RF
models for this large-sample analysis. Inclusion of WRM terms improves the
performance of some models in specific catchments. The LR models of high BFI catchments with relatively high levels of groundwater abstraction show the greatest improvements, and there is some evidence of improvement in LR
models of catchments with moderate to high effluent discharges. However,
there is no evidence that the inclusion of the WRM covariates improves the
performance of LR models for catchments with high surface water abstraction
or that they improve the performance of the RF models. These observations
are discussed within a conceptual framework for baseflow generation that
incorporates WRM practices. A wide range of schemes and measures are used to manage water resources in the UK. These include conjunctive-use and low-flow alleviation schemes and hands-off flow measures. Systematic information on such schemes is currently unavailable in CAMELS-GB, and their specific effects on BFI cannot be constrained by the current study. Given the significance or importance of WRM terms in the models, it is recommended that information on WRM, particularly groundwater abstraction, should be included where possible in future large-sample hydrological datasets and in the analysis and prediction of BFI and other measures of baseflow.
Investigating the effects of intersection flow localization in equivalent-continuum-based upscaling of flow in discrete fracture networks
Authors: Kottwitz Maximilian O. , Popov Anton A. , Abe Steffen , Kaus Boris J. P.
Published: October 2021

Abstract. Predicting effective permeabilities of fractured rock masses is a crucial component of reservoir modeling. Its often realized with the discrete fracture network (DFN) method, whereby single-phase incompressible fluid flow is modeled in discrete representations of individual fractures in a network. Depending on the overall number of fractures, this can result in high computational costs. Equivalent continuum models (ECMs) provide an alternative approach by subdividing the fracture network into a grid of continuous medium cells, over which hydraulic properties are averaged for fluid flow simulations. While continuum methods have the advantage of lower computational costs and the possibility of including matrix properties, choosing the right cell size to discretize the fracture network into an ECM is crucial to provide accurate flow results and conserve anisotropic flow properties. Whereas several techniques exist to map a fracture network onto a grid of continuum cells, the complexity related to flow in fracture intersections is often ignored. Here, numerical simulations of Stokes flow in simple fracture intersections are utilized to analyze their effect on permeability. It is demonstrated that intersection lineaments oriented parallel to the principal direction of flow increase permeability in a process we term intersection flow localization (IFL). We propose a new method to generate ECMs that includes this effect with a directional pipe flow parameterization: the fracture-and-pipe model. Our approach is compared against an ECM method that does not take IFL into account by performing ECM-based upscaling with a massively parallelized Darcy flow solver capable of representing permeability anisotropy for individual grid cells. While IFL results in an increase in permeability at the local scale of the ECM cell (fracture scale), its effects on network-scale flow are minor. We investigated the effects of IFL for test cases with orthogonal fracture formations for various scales, fracture lengths, hydraulic apertures, and fracture densities. Only for global fracture porosities above 30 % does IFL start to increase the systems permeability. For lower fracture densities, the effects of IFL are smeared out in the upscaling process. However, we noticed a strong dependency of ECM-based upscaling on its grid resolution. Resolution tests suggests that, as long as the cell size is smaller than the minimal fracture length and larger than the maximal hydraulic aperture of the considered fracture network, the resulting effective permeabilities and anisotropies are resolution-independent. Within that range, ECMs are applicable to upscale flow in fracture networks.
Predictors of Depression and Suicidal Ideation of Filipino College Freshmen in a Philippine State College
Authors: Alayon Nick D.
Published: October 2021

This study described the prevalence and predictors of depression and suicidal ideation of 365 Filipino college freshmen in a Philippine State College during the academic year 2019–2020. Utilizing a descriptive correlational design, psychosocial predictors were measured using the Bar-On EQ Inventory and participants' socio-demographic profile respectively. Depression and suicidal ideation were measured using Depression, Anxiety, and Stress Scale-21 and Columbia-Suicide Severity Rating Scale respectively. Emotional intelligence and family structure were inversely associated with depression and suicidal ideation while sex was associated with suicidal ideation. Parents/guardian's educational attainment was associated with depression and suicidal ideation. EQ and family structure were predictors of depression and suicidal ideation, while sex predicted suicidal ideation. Prevalent depression, higher suicidal tendencies among female students, and those living alone, and students' underdeveloped EQ point towards an urgency for gender-specific, psycho-socially oriented, and strategic school-based mental health program.

Published: October 2021

Using descriptive-comparative-correlational research, the study aimed to determine the parenting styles based on Baumrind's Parenting Typology and level of self-help skills of kindergarten learners using the Philippine Early Childhood Development Checklist. The dominant parenting style employed by the parents was authoritative when they were taken as a whole and grouped according to sex, employment status, and family monthly income except for the 6,000-10,000Php earners and the single parents who were authoritarian. The learners had slightly advanced development when taken as a whole and grouped according to the aforementioned variables except those raised by guardians who had average development. There was no significant difference in the self-help skills of the learners when they were grouped according to sex, monthly family income, and employment status. However, there was a significant difference when they were grouped according to the marital status of their parents. Lastly, there was no significant relationship between parenting styles and the self-help skills of learners.

This study aimed to elucidate the level of happiness and its influencing determinants among employees (teaching and non-teaching) of Visayas State University, Baybay City, Leyte, Philippines. With the aid of purposive sampling, the study engaged 162 employees as participants in the survey to gather richer information. The study utilized primary data, which were collected through a developed and structured questionnaires. The data were analyzed through descriptive analysis and econometric modeling. Results revealed that non-teaching employees are more likely happy working in a university. It was found out that the predictors of happiness in working in a university are: age, years in service, permanent status, opportunities for promotion, and fair administration. Employees found their respective jobs as challenging, enjoyable and rewarding. However, results showed that income is not a determinant of employees' happiness. Furthermore, employees who are socially oriented and physically healthy are more likely happy workers.
Speciesism and the Wildlife Trade: Who gets Listed, Downlisted and Uplisted in CITES?
Authors: Hutchinson Alison , Stephens-Griffin Nathan , Wyatt Tanya
Published: October 2021

Wildlife faces a number of threats due to human activity, including overexploitation from excessive and/or illegal trade. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is the main international legal instrument to address such overexploitation. However, not all species threatened by excessive trade are protected by CITES, leading to criticism that it is an instrument for the preservation of exploitation as opposed to the protection of wildlife (Goyes and Sollund 2016). This article explores whether CITES classifications can be said to perpetuate speciesist thinking. We highlight which species are more likely to receive protection by analysing which species are listed and how some species move between the CITES Appendices and comparing this to the International Union for the Conservation of Nature’s (IUCN) classifications for traded wildlife. We find that a species’ market value, charisma, and survival status form a complex set of characteristics that lead (or not) to the continual trade of some species, even though they are facing extinction from human consumption.

One of the most significant phenomena in the processing of horticultural crops, leading to the damaging of the fruit, is fatigue due to repeated mechanical stress, which endangers the integrity of the produce, especially during transport. In the event of such damages, the immediate environment of the damaged fruit, or even the entire batch of crops may be in danger, as the biological processes leading to spoilage are not limited to the individual crop damaged. In the case of repeated effects, a force less than the static limit value is sufficient to cause spoilage, but in addition to the load, the material properties of the given crop, as well as the energy balance observed during damage play important roles in determining the mechanical resistance. Accordingly, in our work, a description of the spoilage process is built on the material models most characteristic of the selected crops, on the dissipated energy indicators measured during repeated loads, and on the definition and determination of the spoilage time. In the experiments, the fatigue indices of Golden Delicious apples, making up most of the apple production of the European Union, and of long shelflife Packham pears are compared by setting up linear regression models.

Kutatásunkban az egészségvédő élelmiszerekkel kapcsolatos fogyasztói attitűdök vizsgálatát tűztük ki célul, amelyet a fizikai aktivitás és a táplálkozás vonatkozásában elemeztünk. A vizsgálataink három fázisban valósultak meg. Elsőként netnográfiai (társadalmi interakció vizsgálata a kortárs digitális kommunikációs környezetben – A Szerk.) elemzést végeztünk egyrészt keresőmotorban rögzített adatokkal, másrészt nyilvánosan hozzáférhető közösségi oldalak csoportjaiban elhangzott posztok és hozzászólások tartalomelemzésével. Az online térben jelenlévő fogyasztók érdeklődési körét, valamint annak változásait detektáltuk az egészségtudatos táplálkozás és a fizikai aktivitás közös halmazában. Míg a találati számok évről évre változatos ütemű növekedést mutatnak, addig a tartalmak viszonylag stabil csoportokba koncentrálódnak. Ennek alapján az online térben négy fő témakör különíthető el az egészséges táplálkozás és a mozgás közös halmazában: Edzéstervek receptekkel, Javaslat kérése, Tanácsadás nyújtása, Motiváló példák. Kutatásunk második fázisában fókuszcsoportos interjúkat bonyolítottunk le. Megvizsgáltuk, hogy a rendszeres testmozgás milyen hatással van az egészségvédő élelmiszerek vásárlására és fogyasztására, továbbá, hogy ennek milyen vonzatai élnek a fogyasztók által egészségesebbnek vélt táplálkozás kialakításában és fenntartásában. A vizsgálatokba 7-7 főt vontunk be, előzetes kritériumok alapján. A csoportokba kerülés differenciáló tényezője a rendszeres fizikai aktivitás végzése, így egy aktív és egy passzív csoportot alakítottunk ki. A különbségek és jellegzetességek azonosítása megalapozó jelleggel bírt kvantitatív kutatásunk kialakításában. Kutatásunk harmadik fázisában Magyarországon elsőként adaptáltuk a Consumer Style Inventory (CSI)1 tesztet az egészségvédő élelmiszerekre vonatkozóan, amelynek végső változata 25 tételt tartalmaz. Ezen felül vizsgáltuk az egészséges táplálkozásra való áttérés módjának különbségeit. Az Eurobarometer felmérései alapján a fizikai aktivitással és az ülő életmóddal kapcsolatos tételeket fogalmaztunk meg, amelyeket az elemzésben a háttérváltozókhoz soroltunk. A felmérés, a nemekre vonatkozóan reprezentatív, 300 fős mintát alkot. Feltáró kutatásunkban főkomponens-elemzéssel azonosítottuk a CSI-ban megjelenő attitűdöket, majd K-means klaszterelemzéssel csoportokat képeztünk. Ennek alapján négy homogén fogyasztói csoportot azonosítottunk az egészségvédő élelmiszerekkel kapcsolatos attitűdök szempontjából: Érdektelenek, Egészség-orientáltak, Változatosságot keresők, Bizonytalan márkaválasztók. Eredményeink szerint az ülő életmód nincs befolyással, míg az egészségesnek vélt táplálkozás, a fizikai aktivitás rendszeressége és időtartama jelentős hatással van az egészségvédő élelmiszerekkel szemben mutatott attitűdökre.

Dolgozatunkban a fagyasztva szárított őrölt alma (7%) és brazil diómag (5%) kombinált felhasználásával készült sült baromfitermékek vizsgálati eredményeit mutatjuk be. A recept módosítása olyan töltött húskészítmények előállítását tette lehetővé, amelyek a hagyományoshoz képest előnyösebb fogyasztói tulajdonságokkal bírnak, az illatban alma- és diójegyekkel, enyhén savanykás-édeskés tónussal az ízben és karamell árnyalatokkal a színben. Ezen túlmenően megnövekedett élelmirost-tartalommal, szerves savakkal, fehérjékkel rendelkeznek. Ásványi elemekben gazdagok (Mo, Au, Cu, B, Mn, W, Be, Sn, Fe, Ca, Mg, P). Mindezek a vaj mennyiségének 4%-os csökkenése mellett valósultak meg.

The article deals with the main parameters of the thermodynamic working device for rock destruction due to the implementation of a new method of fuel mixture combustion in shock waves initiated by a high-speed torch burner in gas-dynamic combustion intensifiers. A device for thermal destruction of rocks has been developed, which belongs to the mining industry and can be used for directed impact on rocks when they are destroyed by hot gas jets in mining, stone processing and construction industries. Also, installed coaxial to the nozzle, with increasing inside diameter, a cylindrical nozzle, with two cascades of ejection holes - the first cascade is made at a distance from the Laval nozzle, equal to the distance to complete expansion of the jet of the torch, then, the accelerating section of the nozzle and the new, formed by burning the unburned fuel, jet of the burner. It is found that the cross sectional area of the inner hole of the cylindrical nozzle, is made with an excess of the area of the critical cross section of the nozzle Laval burner 2.5-3 times, in which, because of the rapid expansion of the gas flow in the nozzle, there is turbulization, with the formation of a powerful zone of heating of the gas flow and the appearance of a standing detonation wave in it. The drilling angle of the ejection holes of the first stage is 45-50º to the axis of the nozzle, which serves for ejection of atmospheric air, the oxygen of which reacts with the surplus of combustible in the main jet of the burner and the formation of a more powerful jet.
