Thermosolutal natural convective transport in Casson fluid flow in star corrugated cavity with Inclined magnetic field

Abstract

Diffusion mechanism generated because of thermal and solutal buoyant forces in star corrugated cavity filled with Casson liquid is envisioned in this study. Magnetic field making angle of inclination with enclosure is also taken into account. Rectangular plate with isothermal and isoconcentration distributions is installed. To measure optimized variation in associated distributions all the extremities of enclosure are kept at cold temperature and zero concentration. Governing equations are modelled by incorporating conservation laws. After then, complexly formulated model equations and their associated boundary constraint are change in dimensionless structure by obliging variables. Numerical simulations are performed by opting finite element based commercial software renowned as COMSOL. Domain is discretized in the form of triangular and rectangular elements by executing hybrid meshing. Afterwards, non-linear solver (PARADISO) is capitalized to handle system of non-linear equations. Mesh independence test is carried out to assure credibility of conducted simulations. Comparison of results with published literature is also displayed. Graphical and tabular representation describing change is associated fields (velocity, temperature and concentration) against wide range of involved parameters. Change in kinetic energy along with average Sherwood and Nusselt number against different magnitudes of Casson parameter is divulged through tables.
