Axisymmetric Channel

The effect of the jet flowing out from the gas generator through a narrow annular gap, on the shockwave structure of the flow in the axisymmetric channel of variable section is studied. The effect of the gap size is investigated. The possibility to control the shock-wave structure of supersonic flow in the channel and creating of transonic area using pulsed-periodic energy supply and jet is studied.

AbstractThe results of numerical modeling of laser energy supply in a supersonic flow are presented. In contrast to the common approach, in the new calculation model, not only the absorbed power is taken into account, but also the plasma breakdown impulse in the domain of emission focusing does. The value of the impulse is determined using the model of radiation absorption behind the front of the laser-supported detonation wave. An analysis of the results is presented.

Expanding Channel

The effect of influence of the parameters of similarity on the value of the exergy for supersonic flow in a channel of variable section with a pulsed-periodic energy supply is studied. The specific force acting on the walls of the expanding channel in dependence on the position, length of the zone of pulse-periodic energy supply, the Strouhal number and the Mach number flow is investigated. The following correlation is established: the specific force is increased and the exergy of the flow is used better with decreasing length of the zone of energy supply and with decreasing of distance between the zone and the place of beginning of the channel expansion. Raising the temperature at a single energy supply pulse may be considered as factor which increases specific force. It takes place at lower frequencies
