对六氟化硫（sf6）作为空气替代品的效果进行了数值研究。无粘结果的翼型表明，跨音速的情况下，冲击位置计算sf6是大大不同于在空气中，并逐步向前移动的翼型上的自由流压力增加，真正的气体效应变得更加明显。
Numerical study is presented that investigates effects of using sulfur hexafluoride, SF 6 , as a substitute for air. Inviscid results for airfoils indicate that for transonic cases the shock location calculated for SF 6 is vastly different from that in air and moves progressively forward on the airfoil as the freestream pressure is increased and real gas effects become more pronounced.
