Laminar Boundary Layer in Two-Dimensional Detached Flows

A new approach to the calculation of the laminar boundary layer in a two-dimensional detached fluid flow with the use of two or three integral relations representing the velocity profile of this flow in the form of a definite-degree polynomial is proposed. The initial problem on the indicated layer is defined by the system of two or three ordinary differential equations. The Howart, Tani, and Gortler flows with a decreasing velocity and the flows whose velocity initially increases and then decreases (the Curle flow, the transverse flow around a circular cylinder, and the flow around a sphere) were considered. A comparative analysis of the results of calculations of these flows has shown that the approach proposed allows one to practically exactly determine the point of separation of the boundary layer in them.
