Abstract

A new structural design known as “fillet” on the cavity’s edges is incorporated to enhance the computational and physical domain. For momentum, concentration, and temperature distribution, a Galerkin finite element discretization with quadratic interpolation functions is utilized, and for pressure distribution, we use linear interpolation functions. Elements in the shape of triangles and rectangles are used to discretize the domain. The PARADISO matrix factorized-based nonlinear solver and the Newton method are used to solve nonlinear discretized problems. The analysis of several factors such as Hartmann number (0-50), Rayleigh number (10^4-10^6 ), Lewis number (0.1-10), and inclination angle (0°-90°) is conducted to investigate the impact of flow on streamlines, isotherms and isoconcentration patterns and graphical and tabular representations are used to show the local heat transfer, kinetic energy, and mass fluxes. It is found that heat and mass transfer rate decreases for the variation in Hartman number, and has opposite trend for the variation in Lewis number. Our findings shed light on how DD processes behave in cavities that are exposed to magnetic fields, and they may be useful in optimizing and designing MHD devices for commercial use.
