Abstract
We present here a numerical study of laminar doubly diffusive free convection flows adjacent to a vertical surface in a stable thermally stratified medium. The governing equations of mass, momentum, energy and species are non-dimensionalized. These equations have been solved by using an implicit finite difference method and local non-similarity method. The results show many interesting aspects of complex interaction of the two buoyant mechanisms that have been shown in both the tabular as well as graphical form.

The free convection flow associated with heat-rejection systems for long duration deep ocean power modules where the ocean environment is stratified, (Yang et al, [1])
For all X, here we propose to integrate the local non-similarity partial differential equations (16)–(18) subjected to the boundary conditions (19) by implicit finite difference method together with Keller-box elimination technique, which was first introduced by Keller [14]
Summary
Many free convection processes occur in environments with temperature stratification. The free convection flow associated with heat-rejection systems for long duration deep ocean power modules where the ocean environment is stratified, (Yang et al, [1]). Stratification of fluid arises due to temperature variations, concentration differences or the presence of different fluids. Cheesewrit’s [2] work and of Yang et al [3] showed that similar solutions were not possible. This fact is supported by Eichhorn [4] and by Fujii, et al [5] and they developed series solutions to account for the nonzero leading edge temperature difference. Eichhorn [4] had calculated
