摘要：
Nonequilibrium flows of a rarefied polyatomic gas through a diverging nozzle under the effect of dynamic pressure are studied. Even in a diverging nozzle, there arises a possibility of occurring choking phenomena if a gas at the inlet of the nozzle is in a nonequilibrium state. And the controllability of gas flows in a nozzle by manipulating the temperature of molecular internal modes such as molecular rotation and vibration is discussed.
