PHYSICOMATHEMATICAL MODEL OF THE WORKING PROCESSES OF A SLIDE-VALVE COMBUSTION CHAMBER OF CONSTANT VOLUMEV. I. Bogdanov and D. V. Kuvtyrev UDC 621.43.056 A physicomathematical model of the working processes of a constant-volume combustion chamber, which can be used in promising power plants with a pulsating working process, has been created. A computational experiment the results of which coincide in the main with the data of experimental investigations has been carried out.
