摘　　要：使用二维不可压紊流边界层的积分方法,通过流量守恒方程将主流与边界层联系起来,并使用适用于分离区的积分法补充经验关系式,能有效地计算带分离的二维直壁扩压通道内边界层的增长,从而得到扩压器的压力恢复等特性。After the integral method of two-dimensional incompressible turbulent boundarylayer is presented, the core flow and boundary-layer are connected by means of flow rate equation. Then, the practical relations dealing with integral quantities are used to form the ordinary differential equations. The procedure can effectively be used to compute the development of boundary-layer with separated region in two-dimensional straight diffusers. So the properties such as pressure recovery can be achieved.
