An approximate method to calculate the laminar boundary layer and its separation point. I  The method based on the local characteristics of the boundary layer
Abstract
In this report, a momentum integral equation is solved by using a quasisimilar velocity profile of the boundary layer, under the assumption that the characteristics of the boundary layer depend only on the local Reynolds number and the local pressure gradient parameter of the reference point. The velocity profile has two parameters, one of which is an exponent index of the nondimensional distance from the wall and is determined by examining the exact solutions which were obtained for particular flow cases, and the other is Pohlhausen's parameter and can be obtained from the equation at each section along the surface. The results thus obtained are used for the estimation of the separation point of various flow configurations involving those of a circular cylinder and an elliptic cylinder which has not so large eccentricity. The method is found to give satisfactory results in spite of its simplicity.
