NUMERICAL AND ANALYTICAL ESTIMATION OF PARAMETERS OF PULSED ENERGY SOURCES WHICH DO NOT LEAD TO LOCKING OF SUPERSONIC FLOW IN CHANNELS OF VARIABLE SECTION
In this paper the pulse energy supply into the channel of variable cross section was studied. The approximate formulas were obtained for the value of the input energy, corresponding to the maximal distance which the shock wave from a pulsed power source reached upstream, as well as full power, energy supply period corresponding to the conditions of closing the channel. The applicability of the analytical relationships is confirmed by numerical calculations based on the Euler equations in a quasi one-dimensional approximation.
