DYNAMIC CHARACTERISTICS OF PULSATING TURBULENT FLOW 
OF COMPRESSIBLE GAS IN A CHANNEL

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.
