ABSTRACT
This paper presents the simulation of laminar natural Convection in square cavity with a wavy wall. The cavity consists of one wavy wall and three straight walls. Two vertical walls kept isothermal and one of them is wavy (right). Two horizontal walls are considered adiabatic. The governing equation in primitive variables (u,v,p,T) are solved numerically using an implicit fractional step method. The current method was developed for use on an unstructured grid made up of triangles. The basic principles of this method are that the evaluation of the time into intermediate steps. Result are presented in the form of local and main Nusselt number distributions for various Rayleigh number and for Prandtl number 0.71.streamlines and isothermal lines are also presented for different values of amplitude.
