理想气体
Abstract: Using compensate factor constrictive coefficient to revise perfect gas equation and calculate the measure of natural gas's standard volume, working's status compensate factor can make out similar calculate change by R-K equation.
采用具有补偿因子压缩系数修正的理想气体状态方程,实现对天然气标方计量的计算.工况状态压缩系数的计算由R-K方程近似计算迭代求出,计算误差为0.1%。
Dissociation and ionization of air bring on lower drag coefficients of the orbiter than that obtained from perfect gas model, while the location of pressure center moves forward.
