Study on the energy conversion in plasma flow through a magnetic field in a shock tube

Analytical apd experimental study of ionized plasma flow through magnetic gasodynamic channel (MGDC) has been carried out. The MGDC is joined to the face end of a shock tube. Plasma formed during shock wave reflection from the face end flows through MGDC to a receiver. A quasimonomeric model of the process is suggested. The problem of plasma flow time through MGDC is analyzed. The process of plasma flow formation in MGDC and the effect of the intensity of magnetic gasodynamic interaction on the process is investigated. Experimental data on the flow parameter distribution in MGDC are obtained. A monomer model of ionized gas flow through reflecting nozzle and MGDC joined to the shock tube, is suggested. The calculation results are compared with the experiment. It is shown that at B=O a satisfactory agreement is observed. At B not equal O a qualitative coincidence of wave pictures only for initial time moments (start processes) is observed; at later time moments (during brake wave formation), as shown in the experiment, the dimeric effects, which are not taken into consideration in the calculation, play a significant role
