- Abstract
A method was developed to calculate the discharge process in PDHRPM with regenerative heat exchange, taking into account the pressure losses due to the heating of the fluid in the working cavity. The analysis, based on a numerical experiment, of the existing sources of pressure loss during the discharge process allowed to determine that the largest contribution to the pressure loss (90% or more) depends on the local valve resistances. Relative pressure losses due to heating of the working fluid increase during the discharge process and become significant at the end of the process. The average integral relative pressure loss due to the heating of the working fluid is about 5%, second only to the relative losses due to the local resistances, and its influence decreases with increasing speed.
