Abstract

The paper presents the analysis of influence of the method of calculating the heat transfer coefficient on mathematical
modeling of the process of reverse expansion of ammonia in the working chamber of the reciprocating compressor
stage (in the area of wet steam). Alternative variants of film and drip schematization of the heat exchange process
are considered. The mathematical model is based on the equations of the first law of thermodynamics for a body of
variable mass, the equation of state of a real gas, the Clapeyron–Clausius and Newton–Richman equations. Based
on the results of the computational and parametric analysis, the applicability of known methods for calculating the
heat transfer coefficient to the object under consideration is evaluated.
