Abstract

Similarity numbers of the processes of compression of real gases in the stages of centrifugal compressor machines are given. A method for setting up promptly the thermal and calorific equations of state of the mixtures of real gases for the prescribed region of operation of a compressor machine is proposed. A procedure for processing of experimental data obtained in gasdynamic tests with mixtures of real gases and for reduction of the results obtained to the nominal conditions of operation of the flow part is presented.
