Computational Investigation of Natural Convection heat transfer Coefficienton Extended Vertical Base Plates

In this research, Computational analysis of the laminar natural convection on vertical surfaces has been done. Natural convection is observed when density gradients are present in a fluid acted upon by a gravitational field. Our example of this phenomenon is the heated vertical plate exposed to air, which, far from the plate, is motionless.The CFD simulations are carried out using Fluent software. Governing equations are solved using a finite volume approach. Coupling between the velocity and pressure is made with SIMPLE algorithm. The resultant system of discretized linear algebraic equations s solved with an alternating direction implicit scheme. Then a configuration of rectangular fins is put in different ways on the surface and natural convection heat transfer coefficient on these no slope surfaces is studied and finally optimization is done.
