摘要: Abstract An analysis of combined forced and free convection in a vertical parallel-plate channel with prescribed wall heat fluxes is performed by considering fully developed flow taking into account the effect viscous dissipation. It shown that condition cannot be accomplished if streamwise change occurs. analytical solution momentum balance energy equations found perturbation method. In particular, heating treated as base transfer process. Then, buoyancy accounted for expressing fluid velocity temperature power series respect to ratio between Grashof number Reynolds number.
