Free convection in trapezoidal enclosures has received considerable attention because of its importance in several thermal engineering problems, for example, in the design of electronic devices, solar thermal receivers, uncovered flat plate solar collectors having rows of vertical strips geothermal reservoirs etc. In my work the title named "Analysis on MHD Free Convection Flow Within Trapezoidal Enclosures" has been studied. In this study, free convection within a trapezoidal enclosure for uniformly heated bottom wall, insulated top wall and isothermal side walls with inclination angles (f)...
