Performance of flow and heat transfer analysis of mixed convection in Casson fluid filled lid driven cavity including solid obstacle with magnetic impact

Abstract In this study, the heat transfer and fluid flow characteristics of mixed convection in a double lid driven cavity containing conducting solid obstacle presence magnetic field is numerically investigated. The left right vertical walls are isothermally heated cooled respectively while horizontal thermally insulated. A cylinder positioned at centre cavity. Mathematical model has been developed considering non-Newtonian Casson solved with finite element method based on Galerkin residual technique. simulated numerical results obtained through streamlines, temperature contours average Nusselt number for set dimensionless parameters discussed elaborately to make effective usability different industrial engineering processes. special cases compared existing results. It observed that thermal fields were influenced significantly by Reynolds any parameter. intensification streamlines strengthened parameter isotherms. Moreover, enhancement due increased expedites reverse trend higher Hartmann number. addition, appropriate direction provides better rate.
