The problem of the thermal turbulent boundary layer under the influence of strong adverse pressure gradients near separation is analysed by the method of matched asymptotic expansions. The limit corresponding to the neighborhood of separation, as formulated by Afzal [3], is employed. The thermal boundary layer problem is analysed using the appropriate inner and outer expansions (both above the thermal wall layer). It is found by matching that there exists an inertial sublayer where temperature distribution obeys the inverse half power laws. The comparison of the theory with the measurement shows that the slope and intercept of the wall (inner) law may be regarded as universal numbers, whereas the intercept of outer law shows a linear dependence on τw/δpx.

This paper presents the classical approximation scheme to investigate the velocity profile associated with the Falkner–Skan boundary-layer problem. Solution of the boundary-layer equation is obtained for a model problem in which the flow field contains a substantial region of strongly reversed flow. The problem investigates the flow of a viscous liquid past a semi-infinite flat plate against an adverse pressure gradient. Optimized results for the dimensionless velocity profiles of reverse wedge flow are presented graphically for different values of wedge angle parameter β taken from 0≤β≤2.5. Weighted residual method (WRM) is used for determining the solution of nonlinear boundary-layer problem. Finally, for β=0 the results of WRM are compared with the results of homotopy perturbation method.
