摘要: 利用双压力传感器的方法测量了喷气Z箍缩负载的气流马赫数。测量得到的气流马赫数最高可达到4.25，它和定常计算的结果4.8很接近，这表明可以用定常计算来估算喷气Z箍缩中超声速喷嘴产生的气流马赫数。Abstract: The Mach number of the gas flow from the supersonic nozzle in a gaspuff Zpinch was determined by the two pressure transducer method. The measured Mach number rises with time and reaches to a maximum value of 4.25 that is close to 4.8, the value from a steadystate gas flow calculation. This result shows that the steadystate gas flow calculation can be used to estimate the Mach number of gas flow from a supersonic nozzle in gas puff Zpinch.
