Analysis of the influence of gas dynamic processes on temperature stratification in an energy separation device, taking into account Bernoulli's law and Joule-Thomson effect

The article provides an analysis of a number of gas-dynamic processes affecting the efficiency of the gas-dynamic temperature stratification device. The relevance of the study is due to the need for a more accurate description of the processes of gas-dynamic temperature stratification in energy separation devices, which is important for improving the efficiency of heat exchange and aerodynamic systems. This article is aimed at identifying patterns of energy redistribution in the flow, taking into account the Bernoulli law and the Joule-Thomson effect, as well as analyzing their impact on temperature gradients inside the gas-dynamic temperature stratification device. The study employs mathematical modeling conducted within the STAR-CCM+ framework, enabling a thorough exploration of gas flow characteristics, as well as variations in velocity, pressure, and temperature throughout the system. The article presents the results of a numerical experiment, reveals the mechanisms of influence of the main gas-dynamic effects on temperature stratification, identifies key dependencies between the input parameters of the device and the flow characteristics, and substantiates the possibility of targeted optimization of energy separation. Mathematical models are derived, supplemented by equations that take into account the role of Bernoulli's law and the Joule-Thomson effect. The corresponding equations are considered. The materials of the article are of practical value for the development and improvement of energy separation devices, optimization of working processes in gas-dynamic systems and increasing the efficiency of temperature stratification in aerodynamic installations for use in the real sector of the economy.
