Abstract : A new approach to the solution of laminar boundary layer equations is presented. This method consists in reducing the fundamental boundary layer equations to a universal form by transferring the parameters expressing the influence of the external conditions, characteristic of each particular problem, to the number of independent variables. The approach is based on the use of the similarity concept generalized in the sense described in the paper. A universal equation, nondependent on a given velocity distribution U(x) on the outer boundary of the boundary layer, is derived and integrated in oneparameter and twoparameter approximations by means of a BESM2 computer. The generalized similar solutions of the type obtained may be obtained for threedimensional laminar boundary layers in an incompressible fluid, flows of homogeneous gas, equilibrium dissociating gas flows in magnetohydrodynamic boundary layers in conducting fluid, and also for a turbulent boundary layer.
