Thermal management of MHD nanofluid within the porous medium enclosed in a wavy shaped cavity with square obstacle in the presence of radiation heat source

In this manuscript, we present nanofluid thermal management inside a porous media including magnetic force and radiation heat sources. The systems of PDEs were changed into the non-dimensional form by means of the suitable transform. To gain the outputs, control volume finite element method (CVFEM) was utilized. Radiative source term was involved in final PDEs. Isotherms and streamlines are plotted to demonstrate the variation of Hartmann number, radiation factor, buoyancy and nanoparticles' shape on nanofluid behavior. Outputs demonstrate that convective mode becomes stronger with augment of shape factor. By involving source terms of magnetic field, conduction becomes more effective. Average Nusselt number grows as enhancing the shape effect parameters “m”, Radiation effect and Raleigh number. As increasing Radiation and Raleigh parameters average temperature deceases gradually. The comparative study is also presented, which shows the reliability and efficiency of the CVFEM. Graphical study also shows strengthen of suggested technique.
