Discussion: Finally, we note that Eqs. (8.2),(8.6),( 8.10)are not limited to normal shock waves; they describe the changes that take place in any steady, adiabatic, inviscid flow where only one direction is involved That is, in Fig.8.3 the flow is in the x direction only. This type of flow, where the flow-field variables are functions ofx only, p=p(x), u=u(x), etc. ], is defined as one- dimensional flow. Thus, Eqs. (8.2),(8.6), 8.10)are governing equations for one-dimensional, steady, adiabatic, inviscid flow 讨论:最后,我们应注意,方程(82)、86)(810并不只适用 于正激波,他们描述了只包含一个方向的定常、绝热、无粘流 动。在图8.3中,流动只沿x方向进行。这种类型的流动被定 义为一维流动,其流场变量只是x的函数[p=p(x),u=u(x)等 等]。因此,方程(8.2),(86)(8.10)是一维、定常、绝热、无 粘流动的控制方程。Discussion: Finally, we note that Eqs.
