Approximate solution of a laminar boundary layer on moving surfaces without use of integral relations

A method for quick estimations of laminar boundary layer characteristics in incompressible fluid on a moving wall is presented. The method is a generalization of methods proposed by Shvets [1], Targ [2] and other and it does not use integral relations. All results of the method are obtained for permeable surfaces with possible blow or suction of the same fluid. Primary polynomial approximations of longitudinal velocity profile within boundary layer contain coefficients, which depend on longitudinal coordinate. Cases when basic differential equation is solvable in quadratures are established. Influence of primary polynomial approximations on friction drag coefficient for moving flat plate is studied.
