DYNAMIC CHARACTERISTICS OF PULSATING TURBULENT FLOW OF COMPRESSIBLE GAS IN A CHANNEL E. P. Valueva UDC 531/534 A model of turbulent transfer that allows for the effect of flow-rate oscillations on the turbulent stress is used to investigate pulsating turbulent flow of a compressible gas in a narrow channel. An algorithm for solving numerically the system of equations that describes this process by the finite-difference method with the use of an implicit iteration scheme is proposed. The effect of operating parameters on the amplitude-frequency characteristic is considered. JEPTER74920199916 JEPTER7492016
