EFFECT OF SURFACE ENERGY PULSES ON SUPERSONIC FLOW IN A CHANNEL OF VARIABLE CROSS SECTION

The infl uence of a surface pulse-periodic supply of energy on the formation of shock-wave structures in a plane channel of variable cross section has been studied. Energy is supplied to the constant cross-section units of the channel with the flow Mach number M = 2. The time-average supplied power corresponds to the combustion of hydrogen with the excess-air coeffi cient from 1 to 10. The problem is solved within the framework of the Euler equations. A dimensionless approach is used to analyze the effect of sources. The applicability of the analytical relations obtained is confi rmed by numerical solution of two-dimensional Euler equations.
