对于沿一条流线上的任意两点,有 2(y+1)a*2 +- const y-12y-122(y-1) (8.36) r+ 2 const 2(y-1) (8.37) Clearly, these defined quantities, ao and a*, are both constants along a given in a steady, adiabatic, inviscid flow. If all the streamlines emanate from the same uniform freestream conditions, then ao and a' are constants throughout the entire flow field.很明显,a和a*为定义的量,沿定常、绝热、无粘 流动的给定流线为常数。如果所有流线都来自于均匀自由来 流,则ao和a*在整个流场为常数。const a u a u a = − + + = − + + − 2( 1) ( 1) * 1 2 1 2 2 2 2 2 2 2 1 2 1     对于沿一条流线上的任意两点,有: (8.36) const a a = − = − + 1 * 2( 1) 1 2 2 0    (8.37) Clearly, these defined quantities, a0 and a* , are both constants along a given in a steady, adiabatic, inviscid flow.
