Abstract

In this paper, we are performing a numerical simulation of unsteady plumes for driven thermal high convection dominated flows. These problem results of practical interest, in order to determine the efficiency of heat storage, flow conditions inside electronic components, determining the durability of the equipment, etc. Results for Rayleigh numbers in the range of are presented. In this case, an intermittent spatial transition from laminar to turbulent flows takes place; therefore, high accuracy of spatial and time discretization is required. In this paper, we use finite differences and a fixed-point iterative method. This method has shown to be robust enough to handle high Rayleigh numbers been able to simulate these kinds of phenomena. When working with high Rayleigh numbers and since we have to arrive to a large value of t (time), at each iteration in time, we have to solve a very large system of linear equations.
