Abstract
This work develops an outcome to momentum and energy equations of boundary layer, both presented by White (1991). The results were obtained by variations in freestream velocity over a flat plate. The Mach number varieties between 0.3 and 0.9, also variations in angulation are made where the angle of attack of the plate had various values in range, approximate, between -18º to 10°. For that variation in angle of attack the flow is considered to be Falkner-Skan flow type. The results in Python displayed good precision for the method used. Articles and books of compressible flows were not found for comparison. The work presented a different method for computational calculation of boundary layers, which is different of the articles and books in the literature use finite elements methods. The method used in this work generated faster results convergence and used less computational resources
