Real fluid thermodynamics is the study of the thermodynamic behavior of fluids that exhibit non-ideal behavior, such as deviations from ideal gas behavior, intermolecular forces, and non-negligible volume effects. It involves the application of thermodynamic principles to analyze and understand the behavior of fluids in various conditions, including temperature, pressure, and volume. Real fluid thermodynamics is important for the design and optimization of various engineering systems, such as power plants, turbines, aircraft engines, refrigeration systems, and chemical processes. The Real fluid thermodynamics modeling for multicomponent systems is an high tech technology which will help more understanding of fluid behaviors in various industies and lots of reserch companies work on this to develop more tools for that.
