Abstract
The formation of compression waves during cyclic pulsating combustion is the process that fundamentally distinguishes it from the stationary combustion. The paper considers the interaction of compression waves with the walls of the gas duct of a pulsejet engine having a double bend when deflagration combustion is realized. The computational model is based on the replacement of pulsating combustion by pulsating heat input. The experimental results showing the importance of taking into account the motion of compression waves are also given. The results obtained allow one to develop new design solutions for gas ducts of pulsejet engines realizing the potential of compression waves for the sake of achieving higher specific characteristics.
