THERMODYNAMIC BASIS AND EFFICIENCY OF THE USE OF TERMINAL GASES IN HEAT ENGINES
Keywords:
Heat engine, triatomic gases, thermodynamics, working substance, supercritical co₂, energy efficiency, molecular structure, ideal gas law, alternative energy, environmental safety.Abstract
This article examines the possibilities and limitations of using triatomic gases in heat engines. The thermodynamic basis for using triatomic gases (e.g., CO₂, H₂O vapor, N₂O) instead of traditional diatomic gases (in particular, air), their heat capacity, molecular motion, and deviations from the ideal gas law are analyzed. Also, experiences of using triatomic gases in modern energy systems using the example of supercritical CO₂-based cycles are presented. The article highlights the advantages and disadvantages of these gases in terms of efficiency, environmental safety, and maintenance. The results of the research will serve as the basis for future scientific and technical research on the use of triatomic gases.
