法方程

• In this thesis , different types of stability equations , including orr - sommerfeld equation ( ose ) and parabolized stability equation ( pse ) based on the “ slow change ” hypothesis and the local method equation which is computed in local range , are derived from navier - stokes equation with “ small disturbance ” hypothesis
  本文从navier - stokes方程出发,导出不同形式的流动稳定性方程,包括采用小扰动理论得到的orr - sommerfeld方程( ose ) 、基于流向慢变特性而得到的抛物化稳定性方程( pse )以及在一小范围内计算的局部法方程。
