New Chapters in the Evolution of Taste: How Eighteenth-Century English Salonnières Shaped the Culture of Sociability
Authors: Butoescu Elena 
Published: February 2023

Abstract
In eighteenth-century Britain the term taste was a new vehicle for discerning subtle qualities of an individual mind’s experience of practically anything in the polite world and the world of letters. The term entailed the response of the mind to beauty, and it became popular in each and every genre of writing. The notion of taste acquired a distinctive dimension which effectively disentangles it from the notion of aesthetics emerging early in the nineteenth century as a new area of philosophical enquiry. The eighteenth-century discourses on and ongoing debates over taste and beauty focused on the dominant classicist prototypes of universality, awareness of proportion, harmony and the sense of form and symmetry, principles which were specifically articulated by such Men of Taste as the Earl of Shaftesbury, David Hume and Joshua Reynolds, who had a monopoly on taste. However, the eighteenth century laid the groundwork for an alternative notion of taste, which included women in the realm of theorizing in the taste mode. This article aims to look into the category of exotic taste, and more precisely into the fashionable literary coterie of eighteenth-century England, often presided by women writers such as the Bluestockings Elizabeth Montagu, Mary Delany, Catherine Macaulay, and Hannah More, with the purpose of connecting this type of literary promotion, which was effective in shaping contemporary literary taste, to the theories of taste that anticipated aesthetic judgment in the nineteenth century. Besides, the new social milieu accommodating literary meetings shaped a new discourse which, though ridiculed, facilitated and revitalized conversation in what Hume called “the conversable world” and Samuel Johnson defined as the “clubbable” age. Accordingly, the article will explore the extent to which the discourse employed in such conversations transformed women’s literary taste into an accepted critical category and contributed to the formation of literary reputations.
Is the Quality of Life Objectively Evaluable on Naturalism?
Authors: Vallicella William F. 
Published: February 2023

Abstract
This article examines one of the sources of David Benatar’s anti-natalism. This is the view that ‘all procreation is [morally] wrong.’ (Benatar and Wasserman, 2015:12) One of its sources is the claim that each of our lives is objectively bad, hence bad whether we think so or not. The question I will pose is whether the constraints of metaphysical naturalism allow for an objective devaluation of human life sufficiently negative to justify anti-natalism. My thesis is that metaphysical naturalism does not have the resources to support such a negative evaluation. Metaphysical naturalism is the view that causal reality is exhausted by nature, the space-time system and its contents.
The gist of my argument is that the ideal standards relative to which our lives are supposed to be axiologically substandard cannot be merely subjective expressions of our desires and aversions; they must be (i) objectively binding standards that are (ii) objectively possible in the sense of concretely realizable. The realizability condition, however, cannot be satisfied on metaphysical naturalism; ergo, failure to meet these ideal standards cannot show that our lives are objectively bad.
Axiology and the Problem of Evil
Authors: Crozat Elliott R. 
Published: February 2023

Abstract
In this article, I contend that (a) disagreement over the definition of ‘good person’ indicates a challenge for the probabilistic argument from evil (PAE) and (b) the debate between value monism and value pluralism exposes obstacles for the PAE. I also highlight areas for further axiological inquiry with respect to the problem of evil and related problems. My goal is not to argue that the PAE fails, but to examine the axiology of the argument, to investigate some of its vulnerabilities, and to motivate novel evaluations of it by reframing it as an axiological rather than moral issue.

Published: February 2023

The Kentucky Re-Entry Universal Payload System (KRUPS) is a low-cost space capsule that has been designed to collect flight data. This work focuses on computational fluid dynamics (CFD) simulations of the flow around the capsule at various altitudes along the trajectory path during Earth re-entry. CFD simulations are performed at altitudes of 60 and 40 km by accounting for thermochemical nonequilibrium and surface catalycity using current state-of-the-art hypersonic approaches. The flowfield at all altitudes exhibits significant thermal and chemical nonequilibrium with vibrational temperature lagging the translational temperature in the forebody and exceeding the translational temperature in the wake. Inclusion of surface catalycity influences the heat flux on the surface and the flow temperature in the boundary layer. The number density profiles of nitric oxide molecules and spectral emission computations using the line-by-line radiative solver NEQAIR indicate that higher emissions would occur at an altitude of 60 km in comparison to emissions at 40 km, and spectral intensity would be higher along the stagnation line despite high densities of NO near the edges of the capsule, and that emissions in the 100–400 nm wavelength range are dominant.

Published: February 2023

A dynamic extreme gradient boosting (XGBoost) and MaxLIPO trust region parallel global optimization algorithm is proposed in this paper, and it is applied to the turbomachinery blade aerodynamic optimization coupled with an in-house graphics processing unit (GPU) heterogeneous accelerated compressible flow solver, AeroWhale. The algorithm combines an accurate machine learning regression model, an efficient nongradient optimization method with no hyperparameters, a dynamic update regression strategy, and double convergence criteria to achieve high optimization accuracy and efficiency. The optimization results on the test function indicate that the number of objective function calls is less than 2% of that required by a traditional genetic algorithm, which greatly reduces the optimization time. The dynamic XGBoost model ensures that the regression model accuracy near the optimum is relatively high, which is attributed to the update strategy. The error between the optimal value identified by the proposed algorithm and the theoretical value is only 0.52% after several objective function calls. Finally, the aerodynamic optimization algorithm is applied to the LS89 high-pressure turbine, and the total pressure loss is reduced by 13.16%. The sensitivity of each optimization feature to the objective function is determined, showing that the blade suction surface control point near the trailing edge has the greatest impact on aerodynamic performance.

Published: February 2023

The flame dynamics in the combustion chamber of a hybrid rocket motor were visualized using novel chemiluminescence imaging. A multidirectional visualization system employing [Formula: see text] endoscopes generated images based on methylidyne chemiluminescence (CH*), with one endoscope in the precombustion chamber and two in the postcombustion chamber. Images were collected with a high-speed camera using a 1 ms exposure and a 1 kHz frame rate. Fuel grains having a helical or a conventional circular port structures were assessed, and combustion trials were conducted using a laboratory-scale hybrid rocket motor with oxygen as the oxidizer at mass flow rates from 10.43 to [Formula: see text]: equivalent to combustion chamber pressures ranging from 0.7 to 1.24 MPa. Flame structures were observed during the ignition, combustion, and shutdown stages; and the helical grain generated a larger, more intense flame zone. A proper orthogonal decomposition analysis showed that the helical grains also produced a greater degree of turbulence and stronger oscillations. These results confirm that a helical structure increases the flow turbulence and convective heat transfer in the combustion chamber. These effects lead to higher regression rates and better mixing efficiency that may, in turn, provide greater combustion efficiency at optimized oxidizer/fuel ratios.
Experimental and Analytical Study on the Liquid Film by Jet–Wall Impingement

Published: February 2023

Liquid film cooling by jet–wall impingement on the combustor wall is commonly used in small rocket engines. The heat transfer mechanism inside the liquid film is closely related to the film flow. Therefore, we establish a comprehensive analytical model with reasonable assumptions for the liquid film flow by inclined jet–wall impingement, and we validate it through a series of experiments. It is found that the predicted liquid film dimensions agree well with the experimental results. As the impingement angle increases from 30 to 60 deg, the shape of the liquid film turns from an oval to a circle. With the increase of the impingement velocity from 7.8 to [Formula: see text], the width, length, and area of the liquid film increase. The wall roughness [Formula: see text] ranges from 6.3 to [Formula: see text], which shows negligible effects on the liquid film dimensions. As the surface tension increases from 36.03 to 67.13 mN/m and the viscosity increases from 1 to [Formula: see text], the dimensions of the liquid film decrease. The effect of viscosity is more significant than surface tension within the scope of this experiment. Finally, an empirical correlation for the three investigated film dimensional parameters is proposed.

AbstractIn this paper, we present an integrated workflow utilizing a numerical model to identify optimal operating envelope for horizontal wells producing from dual permeability media. A synthetic dual permeability numerical model comprised of critical components namely: fracture and matrix permeabilities, matrix-fracture conductivity (shape factor), and fracture distribution based on Discrete Fracture Network (DFN) scheme was built. In addition, two horizontal producers completed with Inflow-Control – Devices (ICDs) and as open-hole respectively, are also connected to the model. Rigorous sensitivity analysis is implemented on these key parameters using the dynamic model under Equalspacing sampling scheme with well oil rate as the objective function. Range of values on each variable are typical for naturally fractured reservoirs. In addition, detailed sensitivity on ICD parameters such as flow resistance ratings are performed. Results from the analysis are presented in cumulative probability function identifying most likely, pessimistic and optimistic values.Among all the variables, Matrix-fracture transmissibility has most impact. Unfortunately, it is often neglected when designing horizontal wells in dual permeability reservoirs. Current practice pays most attention on permeability contrast lack of consensus in the industry on best technique for its estimation. Most common methodologies applied are Kazemi and Warren-Roots. Nevertheless, it plays a critical role in describing dual permeability subsurface flow mechanism. Most significantly, it is widely acknowledged that beaning up choke sizes enhances production performance of wells connected to dual permeability. However, in this study, we have been able to establish operating limits for this phenomenon.Matrix-fracture transmissibility could significantly influence a producer, which has not intersected high permeability streaks. Our study clearly demonstrates this observation using high-resolution dual permeability dynamic model. In addition, by performing multi-variate characterization, we establish operating envelope for optimizing well production performance in dual media systems through choke size settings.

AbstractThe problem of wellbore instability is a worldwide technical problem in the field of the drilling engineering and one of the core problems for the safe and efficient drilling. After the drill bit drills the formation and a borehole is formed, the drilling fluid column pressure replaces the support provided by the drilled rock stratum, upsetting the original stress balance of the formation, and causing the stress redistribution of the rock around the borehole. If the redistributed stress exceeds the maximum load that the rock can bear, it will lead to wellbore instability. At the same time, the invasion of the drilling fluid filtrate into the formation will cause an increase in the formation pore pressure and a decrease in rock strength, further aggravating the instability of the wellbore. In tight gas development, the particularity of the drilling of the long-horizontal wells, during which the unstable bedded sandstone is taken as the target layer, the distribution of the secondary stress around horizontal wells, which is very different from that of vertical wells, the complex stress environment of tight gas reservoirs, and the well-developed bedding/fractures all increase the risk of wellbore collapse and instability. Based on the pore elasticity and single structural plane strength theory, this paper establishes a mechanical analysis model for the wellbore stability of horizontal wells in layered shale to analyze the effects of bedding plane occurrence (strike, dip angle), wellbore trajectory (wellbore orientation), and weakening of bedding plane strength on wellbore stability of horizontal wells. Besides, this paper establishes a three-dimensional geomechanical model of Zhongqian 1 block based on the geomechanical modeling technology to precisely characterize the distribution characteristics of mechanical parameters in three-dimensional space to provide technical support for the optimization of horizontal well drilling plan.

AbstractOffshore platforms in Gulf of Thailand have been aging and reaching their end of service life. To safely operate in aging platforms beyond their original intended service life, all possible operation risks need to be assessed through design review, condition assessment, inspection strategy and technique for the platform life extension stage. Qualitative or Semi-quantitative risk assessment was generally utilized by adopting scoring rule based on the condition assessment through inspection data/anomalies. A general subsea inspection campaign requested a costly additional air diving campaign for ACFM for joints with low fatigue life without a consideration of past inspection results. In practice, the routine inspection should be arranged in such a way that the operation risk meets the as-low-as practically possible (ALARP) criteria and yet minimize the cost, time and resources required for inspection. A quantitative risk assessment (QRA) and structural reliability analysis (SRA) are applied within PTTEP to evaluate and predict platform's risk development through time dependent probability of system failure. Inspection strategy including interval (when), locations (where), and suitable equipment and technique (how) are quantitatively incorporated into a mathematical model. The system probability of failure incorporating the system degradation is evaluated and inspection is triggered when the risk exceeds the allowable threshold. A complementary statistical decision model to evaluate the suitable inspection interval considered cost of failure, loss of production, and inspection is also employed. Results of quantitative method shows that the inspection interval can be prolonged, particularly, for well-designed and well-maintained platforms with reducing demand of additional air diving campaign. For most platform with relatively low to moderate consequences of failure, the inspection interval can be extended up until 10 years with routine general visual inspection (GVI), Flooded Member Detection (FMD) operated by remotely operated vehicle (ROV), provided that no significant anomalies are reported during the entire platform life cycle.In Summary, the approaches minimize the demand for additional air diving operation leading a reduction in additional cost, operational risk, and carbon footprint at least 250MT. The offshore structural integrity management and life extension programme for platform after service life by QRA is considered as new leveraged paradigm and delivers the cutting-edge integrity management programme leading to the most optimized operational cost with philosophy of safety and sustainability.

AbstractOil reserves with oil viscosity above 150 mPa·s account for a large proportion of the Bohai Oilfield. However, due to the low mobility of heavy oil, and low sweep efficiency of injected fluid, the recovery factor of heavy oil is always low. A new amphiphilic polymer (activator), which can effectively disassemble the accumulation of asphaltene molecular layer of heavy oil, thus reducing oil viscosity has been developed in the lab and applied for two injection wells in Bohai Oilfield for a pilot trial.In this paper, the pilot trial of heavy-oil activator flooding (HAF) is comprehensively evaluated in both injectivity, production, and interwell connectivity analyses. The apparent injectivity index, Hall plot analysis, injection profile measurement for different layers, and PI test methods are applied to study the seepage resistance build-up effect at injection wells. Waterflooding characteristic curve method is implemented for history matching and oil incremental analysis. The interwell connectivity between wells is characterized by the Capacitance Resistance model (CRM).The injection trials showed great seepage resistance build-up effects at two activator injectors. There are apparent deviations in Hall plots after the activator injection. Activator flooding enables uniform water injection profiles for different layers. The PI tests show that the pressure drop speeds get lowered during the injection period. As for the oil incremental effect evaluation, the theoretical waterflooding characteristic curve function gives an estimation of the incremental oil production to be 1.77×104 m3 during the evaluation period. CRM analysis indicates that the connectivity between injector I2 and producer P4 is higher than that of other wells, and the time lag of getting a response by the activator fluid is smaller than other wells, which is an indication of potential fluid channeling in the flow path. It is validated by the high concentration of produced agent from P4 during HAF.The successful implementation of the activator flooding pilot trial proves that the lab results of amphiphilic polymers can be scaled up to field scale and it plays an important role in the de-risking of full-field implementation. Besides, it shed light upon the effective displacement of heavy oil with a viscosity greater than 150 mPa·s in offshore reservoirs by amphiphilic polymers.
