EFFECT OF A HEAT CONDUCTING HORIZONTAL CIRCULAR CYLINDER ON MHD MIXED CONVECTION IN A LID-DRIVEN CAVITY ALONG WITH JOULE HEATING

Magnetohydrodynamic (MHD) mixed convection in a liddriven cavity along with joule heating is studied numerically. The cavity consists of adiabatic horizontal walls and differentially heated vertical walls, but it also contains a heat conducting horizontal circular cylinder located somewhere within the cavity. The aim of the study is to delineate the effect of such a cylinder on the flow and temperature fields. The governing equations are first transformed into a non- dimensional form and resulting nonlinear system of partial differential equations are then solved by using Galerkin weighted residual method of finite element formulation. The analysis is conducted by observing variations of the streamlines and isotherms for the size, locations and thermal conductivity of the cylinder at the Richardson number…
