Heat Transfer and Liquid Distribution Between Two Moving Porous Surfaces
Medard Marcus Nganbe II, Jacques Hona, Elisabeth Ngo Nyobe and Elkana Pemha

Abstract:
Background and Objective: Fluid flow and heat transfer between two permeable walls are used to model a variety of porous surface mechanisms ubiquitous in engineering and industry. This study deals with a numerical contribution in order to ensure a deeper understanding of phenomena of heat and mass distributions inside a rectangular, porous industrial conduct. The investigation is restricted to find a numerical solution of a two-dimensional flow driven by liquid withdrawal/addition also known as suction/injection through two parallel porous walls which are accelerated and maintained at different temperatures. Materials and Methods: By similarity transformation, the Navier-Stokes equations and the energy equation describing mass and heat distributions inside the channel are reduced to a nonlinear boundary-value problem which is solved applying a numerical integration based on the shooting method. Results: The solution of the problem is expressed in terms of velocity components, temperature and pressure gradients between two opposing permeable surfaces. Conclusion: It is found that positive wall accelerating parameters give the existence of flow reversal. Boundary layers occur inside the channel with the growth of the injection Reynolds number at a fixed positive accelerating parameter and by increasing the suction Reynolds number in the case of a fixed negative accelerating parameter. Thermal boundary layers take place within the channel when the Peclet number approaches the values of 10 and -10 at fixed positive and negative accelerating parameters, respectively.
