A numerical study on developed laminar mixed convection with vertical channel in downflow

In this paper, a numerical study on developed laminar mixed convection in vertical channel is considered. The flow problem is described by means of partial differential equations and the solutions are obtained by an implicit finite difference technique coupled with a marching procedure. The velocity, the temperature and the pressure profiles are obtained and their behaviour is discussed computationally for different values of governing parameters like buoyancy parameter Gr/Re, the wall temperature difference ratio rT and Prandtl number Pr. The analysis of the obtained results showed that the flow is significantly influenced by these governing parameters.
