Sedaghati T1 Approximate Solution of Mixed-Convection Boundary-Layer Flow Adjacent to a Vertical Surface Embedded in a Stable Stratified Medium JF Heat Transfer Research JO HTR YR 2009 FD 2009-11-13 VO 40 IS 8 SP 729 OP 745 K1 homotopy analysis method (HAM); boundary layer flows; numerical solution; stratified medium; heat transfer AB In this paper, the analytic solution of the steady mixed-convection boundary-layer flow through a stable stratified medium adjacent to a vertical surface is obtained using the newly developed analytic method, namely the homotopy analysis method (HAM). The velocity outside the boundary layer and the surface temperature are assumed to vary linearly from the leading edge of the surface. It is found that dual solutions exist, and the thermal stratification delays the boundary layer separation.
The analytic results are compared with the numerical solution (NS) and the comparison demonstrates that there is good agreement between the numerical solution and the HAM solution. Moreover, the convergence of the obtained HAM solution is discussed explicitly. The obtained analytic solution is valid for all values of the dimension-less parameters λ and Pr as is shown below.
