A COMBINED PERTURBATION FINITE-DIFFERENCE PROCEDURE APPLIED TO TEMPERATURE EFFECTS AND STABILITY IN A LAMINAR BOUNDARY-LAYER/

By means of a combined method it is demonstrated for regular perturbat ion problems how the higher order terms of an asymptotic expansion may be determined from numerical solutions of the non-expanded basic equa tions. The method is applied to heat transfer effects in a laminar bou ndary layer and to the analysis of its stability. All first- and secon d-order coefficients of the problem are determined from numerical solu tions of the basic set of equations.
