Two Component Non-Darcian Benard Marangoni Convection with Uniform and Non-Uniform Temperature Gradients in a Composite Layer with Variable Heat Sources/Sinks

In a composite layer that comprises of porous which is sparsely packed and saturated with two component incompressible fluid above this lays the same fluid, variable heat sources or sinks in both layers double diffusive non-Darcian Benard Marangoni (DDNBM) convection investigated. The upper surface has effects depend on temperature concentration, whereas lower rigid. inverted parabolic, parabolic linear profile applied to layer, surrounded by adiabatic boundaries. appropriate thermal numbers (TMANs) are eigen values (EVs) calculated for all three gradients. impact different parameters EVs respect depth ratio examined, thoroughly. effect DDNBM found.
