Influence of intake/exhaust channel lateral profiling on thermomechanics of pulsating flows

The hypothesis that pipeline lateral profiling can be used to regulate pulsating flows in the air-gas systems of energy machines is tested. The results of the physical simulation of gas dynamics and local heat transfer in the intake and exhaust channels of various configurations in the piston internal combustion engine in the conditions of gas-dynamic nonstationarity are presented. We have established that the lateral profiling of intake and exhaust pipes promotes the stabilization of gas flows in the air-gas systems of the engine, and decreases the intensity of the local heat transfer by up to 30%, depending on the initial conditions.
