Effects of an internal cavity on heat transfer and mass transport in partially heated double corrugated domains

Abstract

AbstractThis paper is to investigate the effects of an internal cavity on heat transfer and mass transport in double corrugated domain, which are partially heated below with the consideration of inclined magnetic field. The related mathematical equations of the problem are described by using a dimensionless partial differential system elucidating the physical phenomenon of momentum, thermal and mass transport. The obtained partial differential equations are solved by employing the well‐known finite element method, which is implemented in a commercial software known as the COMSOL. A mesh sensitivity analysis is conducted to assure the credibility of the solution algorithm and involved computational scheme, in which the coupled non‐linear equations solved by the Gauss elimination method through a built‐in non‐linear solver known as the PARDISO. The impact of flow control parameters on numerical outcomes is elucidated using graphical and tabular representation. Additionally, visual representation of key parameters, such as kinetic energy and heat and mass flux coefficient are provided for better comprehension.
