Authors: Pati Biswaranjan , Sharma Bishwajit , Nath Barman Rabindra
Published: August 2019

The phenomenon of fluid flow past a bluff body can be ubiquitously perceived both in nature as well as a multitude of engineering applications. The pragmatic and real-world significance of this problem combined with its simple yet intricate physics has turned the heads of quite a few researchers in the past century. The present study deals with the numerical investigation of flow characteristics around a modified circular cylinder with a slit. The numerical simulations were performed with a finite volume-based solver at a Reynolds number (Re) = 2500 based on the cylinder diameter (D) and the centerline velocity at the inlet, which can be considered as the lower critical value for the dynamic shift from laminar to turbulent flow regime. The upstream and downstream stagnation points on the cylinder surface were connected by a slit. The slits implemented were parallel, converging, and diverging with respect to the direction of flow and amalgamated with one cylinder having no slit, a total of four cases were solved. The windward width of parallel and converging slits was 0.1D and the diverging slit being a mirror of the converging slit. The end-width ratio (Φ) of the converging and diverging slits was 1.5. The results indicated that incorporation of slits in the modified bluff body contributes to drag reduction by the creation of self-issuing jets which affect the wake vortex shedding process downstream of the cylinder. The parallel slit being the most efficacious one leads to the highest reduction of drag due to the formation of smaller sized vortices as compared to convergent or diverging slits in the wake region of the cylinder.

One of the important criteria for designing high speed vehicles is drag reduction and aerodynamic heating. There are plenty of methods available however finding an economical and simple method for drag and heat flux reduction is very challenging. In this paper, the forward facing aerospike for blunt-nosed bodies is introduced at supersonic and hypersonic Mach numbers and tested for drag reduction. Initially, the flow fields are studied around the blunt cone with and without aerospike. In addition, the different shapes and L/D ratios flying at supersonic Mach 2 are computed numerically. The computational simulations is carried out to solve the three-dimensional steady Reynolds-averaged Navier-Stokes equation along with the k-ω turbulence model in computation solver. After comparing the flow properties around the various aerospike models, we have found that the flat aerodisk experiences a drastic pressure reduction on the blunt nose cone but it has relatively less heat flux reduction. Consequently, a slotted aerodisk modification design has been analysed which uses convection flow to reduce heat flux.

Cutting fluids are the category of metalworking fluids which are used in metal machining operation. Application of cutting fluids eases metal removal and enhances the productivity of the industry. Cutting fluids have been used for many decades. Lately the industry is looking toward shifting to using biodegradable cutting fluids. In the last decade many researchers have found that cutting fluids derived from edible oils have a potential to be used in place of the mineral oil based products. However there has not been much reported literature on the surface chemistry of the cutting fluids and how they affect the machining outcomes. In this work experiment was done to study the way in which the viscosity of a non mineral oil based cutting fluid affects the surface roughness of the machining product and the interaction mechanism of cutting fluid with the surface is tried to be deduced from the outcome.

Published: August 2019

The design of automobile intake plays a vital role in the performance of the engine. Any abrupt change in the contour of the intake manifold affects the performance and emission characteristics of the engine. The objective for this research work is to study the flow through restrictor, plenum, and runner for a normally aspirated engine for motorsports application. Restrictor placed in the intake path to achieve the desired value of peak power and torque. In this study, a 20 mm restrictor is used before plenum and runner in compliance with FSAE competition rules conducted by SAE India. In the present study, two novel models of the intake manifold are considered with different plenum geometries. The geometries are modeled using SOLIDWORKS 2014. Meshing is done using ICEM CFD 15.0 and CFD simulations are done using ANSYS-Fluent 15.0. The K-epsilon (RNG) Model is used for simulation with scalable wall function. The two proposed novel intake manifolds were compared on the basis of static pressure, velocity magnitude, total pressure, and turbulence kinetic energy to decide the better model. The effect of the restricted path on the engine efficiency was also analyzed for the better intake manifold model.
Immersed boundary method for flow simulation around horizontal wind turbine
Authors: Jendoubi Aymen
Published: August 2019

Accurate simulation of wind turbine wakes is critical for the optimization of turbine efficiency and prediction of fatigue loads. These wakes are three-dimensional, complex, unsteady and can evolve in geometrically complex environments. Modeling these flows calls thus for high-quality numerical methods that are able to capture and transport thin vortical structures on an unstructured grid. In this work, an immersed boundary (IB) method for solving fluid flow problems of aligned wind turbines under uniform inflow is shown. A finite element method is used starting from a base mesh which does not represent exactly the blade of the wind turbine (non body-conforming mesh). At each time step, the base mesh is locally modified to provide a new mesh fitting the boundary of the rotor blades. The mesh is also locally improved using edge swapping to enhance the quality of the elements and ensure high accuracy of simulation. The methodology is assessed on two different test cases and validated with experimental results.

Authors: Kumar Deepak , Arya Kriti , Sarangi Somnath
Published: August 2019

Research in smart materials, which have fluid-like properties is playing an increasingly dominant role in the fields of aerodynamics as well as in the fluid power systems. Dielectric elastomers are the smart materials, that demonstrate the deformation behavior similar to the smart solids as well as the fluids depending on the environmental conditions. This necessitates a smart deformation approach, which may analyze the deformation of the continua, accurately. In the present paper, we report an alternative modeling method for the deformation of a continua within the framework of the second law of thermodynamics. We adopt a unified continuum mechanics approach to model the deformation of a pre-stretched dielectric elastomer with an application of the electric field. An analytical electromechanical instability model is formulated for a pre-stretched dielectric elastomer through the standard Neo-Hookean, Mooney-Rivlin, and Gent types of energy density functions. A qualitative comparison between these energy density functions is also presented based on the electromechanical instability of a pre-stretched dielectric elastomer. It is shown based on the obtained results that Gent energy density function shows the instability phenomenon with the chain stiffening effect, and the pre-stretching effect may improve the electromechanical instability of the dielectric elastomers.

Published: August 2019

A wide research is going on in the field of renewable energy resources to shelter the scarcity of conventional fossil fuels. As we look back, from the beginning of Earths formation, a tremendous amount of the energy stored inside the earth. Until the start of 19th century man was unaware of this treasure and used lignocellulosic biomass / wood biomass as an energy source of which people unaware of its true potential. But, as fossil fuel sources were discovered, the excavation started to meet the energy demand which obviously replaced the biomass. Then from the petroleum crude oil, petrochemicals took birth and the industrial revolution changed the prospective of entire world. Now, in this first quarter of the 21st century when the population is gigantic and demand for energy sources has increased to the enormous level, fossil fuels are being consumed like never before and now they are diminishing with very fast rate leading towards the energy crisis. So, to overcome this problem; need for the replacements, blends of fossil fuels arises and as a result we are going back in time to utilize another huge source of energy i.e. Biomass. Lignocellulosic biomass can be thermally converted into biofuels by various technologies. One of such most effective and lucrative technology is pyrolysis. Pyrolysis of lignocellulosic biomass convert it into bio-oil, bio-char and pyrolysis gas, these all have high energy content and potential in them. In this deliberated work, authors conducted a pyrolysis experiment on a lignocellulosic biomass which is available as a solid waste on long and far terrestrial region though barely investigated. Temperature of the reaction was set at 500 ºC at which the bio-oil resulted its highest heating value of 17.093 MJ/kg and that of bio-char is 30.768 MJ/kg. Fourier Transform Infrared Spectroscopy (FTIR) showed number of functional groups present and Gas Chromatography-Mass Spectroscopy (GCMS) resulted in huge number of chemical compounds present in the biooil. Then we studied flow behaviour of bio-oil by Interfacial Rheometer and it demonstrated Shear-thinning behaviour. Thus, the study reveals fuel potential of untouched biomass in terms of bio-oil and its transport phenomenon.

Published: August 2019

Energy consumption is increased due to urbanization and developing population. At the same moment society is aware of the decreasing fossil fuel and increasing environmental pollution. Biodiesel is the suitable option to meet future energy demand and improve the domestic economy. Developed countries are using edible oils and the edible oils, which are used, are not sufficient to produce the biodiesel. Non edible oils can be examined as a hopeful replacement for conventional edible oil for biodiesel production. But the edible oil cost is high to be used as fuel. Non edible oil is the right solution to overcome all problems related to the edible oils. There are various plant seeds remain unutilized; these seeds have shown their own potentiality. Due to harmful factors in non-edible oils it is unacceptable for human food. In developing countries non edible oil plants are grown easily. Biodiesel originated from the non-edible plant, is more feasible compared to the alternative fossil fuel. Production of biodiesel using cottonseed oil and rice bran oil appears to be a suitable substitute. The current research paper is aim to review the potentiality of the cotton seed oil and the rice bran oil in production of biodiesel in India.

Authors: Vispoel Bastien , Gamache Robert R.
Published: August 2019

Making reliable semi-classical calculations using the Modified Complex Robert and Bonamy formalism require an intermolecular potential expanded to a high order. Reduced matrix elements (RMEs) need to be computed for each component of the intermolecular potential using the wavefunctions of the states involved in the transition. Calculations for a number of transitions of 13 vibrational bands were performed using the vibrational dependent RMEs and using the ground state RMEs for both upper and lower states. The calculations show that for transitions that obey the sum rules the spectroscopic effect is small.

Published: August 2019

Initial results from time resolved imaging on the formation of a plasma in ambient air, with properties akin to those of the stagnation layer that can be formed at the collision front between two expanding plasmas in vacuo, are reported. Our proposed method for creating stagnation in air at atmospheric pressure is to take a single laser pulse focused into the vertex of a V-shaped channel so the plasma formed on the two surfaces of the V-shaped channel will expand normal to the surface, interact with each-other and potentially stagnate. Time-resolved broadband imaging was used to track the plume expansion and evolution of the plasma.

Published: August 2019

The main objectives of irrigated agriculture are: obtaining the greatest amount of quality products and the preservation of soil fertility. In this case, irrigated crop rotation is one of the factors for the reproduction of soil fertility, favourable phytosanitary conditions in crops and soil protection from erosion. The potential number of lucerne mowing is determined by the thermal resources of the area, and the actual is closely related to the conditions of optimum soil moisture. In the first year 2–4 mowing of lucerne can already be obtained in various areas of the country, over the next two-three years – 4-7 mowing, or 6–10 tons of hay per hectare in the first year and 120–225 centres in the next. Considering the reduction areas of irrigated and drained lands, it becomes relevant to the competent use of the available reclaimed land. The article presents scientifically-based lucerne irrigation regimes that meet the requirements of a plant in water at the lowest cost per unit of production, provides estimated water consumption data and suggests an economical water consumption for obtaining lucerne yield. Considering the irrigation regime of lucerne, the irrigation rate is significant. Since lucerne is a crop with a deeply penetrating root system, watering should be carried out with moistening of the entire root zone. The required amount of water per irrigation depends on the depth of the root system and the water holding capacity of the soil. The study of whether it is possible to obtain the desired effect with smaller irrigation rates is dictated by the increased capabilities of irrigation technology and these issues are presented in the scientific article. The article gives conclusions about the effect of various irrigation regimes on the formation of lucerne yields for hay.

Authors: Reznichenko A A
Published: August 2019

Breeding animals without the use of antibacterial drugs is a relevant branch of modern science, because the entry of national agricultural products into the foreign market provides for the antibacterial drugs absence in raw materials of animal origin. Therefore, in order to improve livability and productivity of animals, it is necessary to constantly monitor the resistance of their bodies, use antibacterial drugs more carefully and eliminate unnecessary or ineffective drugs completely. Thus, an important task facing the veterinary service of the Russian Federation is the complete elimination or reduction of the antibiotics use in animal breeding and the use of drugs that can replace antibacterial ones. We first studied the effect of heteropolysaccharides “raspol” and “gemiv” on broiler bodies. It is established that the used drugs allow eliminating the antibacterial drugs from the broiler ration. In the period of antibacterial drugs exclusion from the broiler preventive treatment scheme these prebiotics cause an increase in poultry gain, increase its livability and natural resistance, while the use of antibiotics in broiler control group negatively affects the body. Recommendations for the use of prebiotics raspol and gemiv in broilers, as an alternative to antibacterial drugs, are provided.

Carrying out researches on extrusion of grain crops with inclusion of vegetable components and assessment of their energy value and competitiveness is an important task. Due to this quality indicator of the ekstrudat on the basis of wheat, barley, oats with inclusion of pulp of green grasses have been defined, the assessment of energy return and energy efficiency ratio has been carried out. The energy value of grain crops increased after extruding by 8.33 – 10.86%. The pulp of green grasses was mixed with seed of wheat or barley or oats in number of 10, 15 and 20% of the mass of mix. After mechanical dehydration of a grass mix the energy value of pulp was 10.68 MDzh/kg. At joint extruding of grain crops with pulp from a grass mix the power value of the ekstrudat decreased and was 0.12-0.21 MDzh/kg. Reduction of power value of the ekstrudat leads to decrease in power return by 0.12-0.21 MDzh/kg. At the same time the energy efficiency ratio is increased by 5.44-6.4%. Increase in power efficiency ratio is connected with reduction of energy input on grain crushing. Extrudat on the basis of wheat mix and 20% of pulp corresponded to the greatest value of energy return and energy efficiency ratio. The equations of linear regression have been received for the mathematical description of change of energy return and energy efficiency ratio. Use of pulp as a part of mix before extruding allows to receive a ready-made product with lower cost price in connection with reduction of grain mass as a part of the ekstrudat.

On the time period 2013-2033 being investigated the demographic model to be constructed allows for the scenario variants to calculate one-year age structures for men and women, one-year age fertility, mortality and net migration rates and all necessary for analysis integral demographic indicators. The results of the multivariate analysis of the demographic processes in Russia in 2013-2033-time period to be carried out are described.

The issues of formation and development of the agri-food market and butter market, in particular, have a multi-faceted character. The growing globalization of the dairy market, as well as the increasing demands placed on milk producers, have led to the fact that those who want to win in the competition for the end user must ensure high quality milk throughout the production chain. Under the quality of milk raw materials for the production of butter one should understand first of all fat content and its fatty acid composition. However, the qualitative and quantitative indicators of raw milk in Russia today cannot ensure a high level of competitiveness of domestic agricultural producers on the world market. The productivity of cows in Russia is much lower than in Europe and the USA. As a result, an important place should be occupied by the issues of improving the quality of raw milk and its compliance with a set of indicators regulated by governing documentation. A certain role in regulating the quality of milk intended for the production of butter, can be played by superficially localized biologically active centres on the body of cows, which can be used to predict the technological characteristics of the produced milk by measuring the level of bioelectric potential and, therefore, to ensure the quality of the finished product already at the stage of forming batches of milk raw materials.

Currently, many issues related to ensuring the enterprise competitiveness, the formation of its market superiority, improving the efficiency of production and development of the pork market, the necessity for its regulation, taking into account the conditions of import substitution, remain far from being resolved. This fact predetermined the research relevance to improve the competitiveness of the pig complex LLC APC “Chistogorsky” (Limited Liability Company Agricultural Production Complex “Chistogorsky”). State policy aimed at economic security, places the global development of pig complexes in all regions of the Russian Federation into the list of priorities. The goal is quite obvious – domestic chilled pork should displace imported chilled and frozen meat. The movement in this direction will provide a large national producer with comfortable conditions for development, and the end user with inexpensive and high-quality products.

The most important condition for increasing the economic viability of the economic entities of the industry is the presence of a competitive domestic breeding base. Analytics showed that at the present time there has been a significant weakening of it, which clearly demonstrates such tendencies as a reduction in the number of breeding farms and, above all, unitary breeding poultry farms, as well as a high dependence on the import of breeding material. The latter circumstance has led to an increase in the cost of both breeding and marketable products, therefore, a decrease in profit margins and the level of profitability. At the same time, an increase in the concentration of the original genetic material among individual manufacturers led to a restriction in the number of crosses used, a decrease in competition in the market for breeding products, and the choice of quality breeding material. The study of the economic viability of poultry enterprises from the perspective of the state of the domestic breeding base, taking into account the development trends of breeding companies in the world, has enabled to identify the fundamental directions for solving the problem under discussion. These include the formation of a competitive domestic breeding base; reduced imports of pedigree products; availability of methodological tools for assessing the genetic potential of poultry; increased investment support from the state and private entrepreneurs; ensuring the availability of credit resources; the introduction of innovative developments that contribute to breeding progress aimed at creating a competitive domestic poultry.

The implementation capabilities of the brand commercial network on the regional market of pasta
Authors: Rozhkova A V
Published: August 2019

At the present time, there is an irregular demand for locally produced pasta products from consumers on the studied regional market. Besides, nowadays we can see the increased competition between food producers on the domestic market. One of the signs of greater competition is the emergence of new product brands and the release of modified products under their current names with similar quality parameters. For this reason, primarily manufacturing companies must build an effective system of network marketing through corporate trade to attract consumers to their products.
