Ⅰ问题的提出在空气动力平面叶栅的数值计算中,通常会提出这样的问题:在给定了叶型后,对自无穷远处流入的,具有进气马赫数M_i和进气角β_i的可压缩气流,来计算其两相邻叶片间的流场和速度场。当然,在一般情况下仍然假设了气流的无旋、无粘等熵等条件。并根据气流在 I. PROBLEM PROBLEMS In the numerical calculation of aerodynamic cascades, a problem that is usually posed is posed by the fact that, given a blade type, the inflow Mach number M_i and the intake angle β_i Compressible air flow to calculate the flow field and velocity field between two adjacent blades. Of course, under normal circumstances, it is still assumed that the flow of non-rotating, non-stick and other conditions such as entropy. And according to the air flow in
