Abstract : A new integral method is presented for the accurate calculation of laminar boundary layer flows. The method is written for unspecified order N of approximation and permits rapid qualitative solutions for low N (1 or 2), and very accurate solutions for high N (3 to 5). Exponentials are used in the velocity approximation and as weighting functions. The resulting integral relations and a simple method for obtaining initial profile parameters are given. Results are presented for continuous and discontinuous external flow and suction conditions and for favorable and adverse pressure gradients covering the spectrum of boundary layer flows from stagnation point to separation.
