Abstract

In this work, we examine the effect the geometrical shape of a partition on the natural convection of two fluid in a square cavity. We considered a square cavity separated in two equal portions with a partition, the two portions were filled with two different fluids. In order to predict the flow, the governing equations of the problem, has been numerically solved with the finite volume method. The influence of the number of Rayleigh has been studied for Ra (10^5 ; 10^6 ; 10^7). In order to focus the study on the impact of partition geometrical shape, various cases has been examined, according to the amplitude and the wavelength. The results state, that for a highest Rayleigh number, the heat transfer rate considerably increases. Moreover, it is interesting to note that to using a corrugated partition can be advised to have a higher transfer of heat.
