Methods of mathematical modeling of thermodynamic processes of piston compressor

An approach to the mathematical modeling of thermodynamic processes of compression of gas or vapor in the cylinder of piston compressor with use of parameters of real gases is presented. A distinctive feature of this approach is an abandonment of equations of state, which are used in traditional models. Theses equations are replaced with the values obtained by interpolation of the experimental data for the individual substances of which the operational body is made. The mathematical model to determine the thermodynamic parameters of the operational body in the cylinder of piston compressor based on heat exchange with the structural members is developed.
