laminar combined magnetoconvection in a wavy enclosure with the effect of heat conducting cylinde

in the current work, a numerical study of the flow characteristics on combined magnetoconvection in a lid-driven square enclosure, differentially heated, is carried out. this problem is solved by using finite element method of the partial differential equations, which are the heat transfer and stream function in cartesian coordinates. the tests are performed for different solid–fluid thermal conductivity ratio, cylinder location and richardson number while the prandtl number, reynolds number, magnetic and joule heating parameters are kept constant. one geometrical configuration is used namely two undulations. the outcome obtained shows that the heat conducting inner square cylinder affects the flow and the heat transfer rate in the enclosure. the trend of the local heat transfer is found to follow a wavy pattern.
