Piston shock wave
WebbA high-pressure field is generated in a circular tube by introducing an unsteady jet from its open end. The head of this jet acts as a piston, driving compression waves ahead of it. The peak value of the induced overpressure is evaluated as a solution of a Riemann problem, wherein the jet head is equivalent to a piston head. The jet head of the driver gas, with a … WebbFor free-piston shock tunnel flows, the nozzle expansion may cause the recombina- tion reactions to proceed so slowly that the free-stream flow is in a frozen dissociated state.

WebbThe method involves producing compressed gas pulses by a compressed gas supply device (32), where the pulses are repeated at a frequency. A striking part (20) is accelerated by the pulses, and an impact body (22) is struck by the accelerated striking part. Impulses of the struck impact body are used for producing pressure waves, and … Webb23 juni 2024 · One-dimensional self-similar unsteady flows behind a spherical or cylindrical shock wave driven out by a piston moving with time according to a power law in a dusty gas is investigated. The medium is assumed to be the mixture of small solid particles of micro-size and a non-ideal gas. The solid particles are uniformly distributed in the …
