isentropic chart , meteorological map that shows the moisture distribution and flow of air along a surface of constant entropy, which is also a surface of constantpotential temperature (the temperature a parcel of dry air would have if brought from its initial state to a standard pressure [1,00...
This low throat pressure is then used as a 'vacuum' source to activate a high speed isentropic flow of air through a power take-off means consisting of a flow rotor which converts the energy of the accelerating linear air flow through it into rotational energy suitable for take-off to do...

8.The results show that the quasi-isentropic compression experiments in the low pressure range can be come ture with explosive-loading device with an air cushion. 并将数值模拟计算结果与实验结果进行了比较,结果表明两者吻合较好,说明在较低压力范围内爆轰驱动加载实验加空腔可以实现准等熵压缩实验。
Compressible flow in which entropy remains constant throughout the flowfield. A slight distinction is sometimes made, especially in Europe, as follows. If the entropy of a fluid element moving along a streamline in a flow remains constant, the flow is isentropic along a streamline. However, the...
