Numerical investigation of natural convection in an inclined enclosure filled with porous medium under magnetic field. (English) Zbl 1113.80016

Summary: In the present study, natural convection of fluid in an inclined enclosure filled with porous medium is numerically investigated in a strong magnetic field. The physical model is heated from left-hand side vertical wall and cooled from opposing wall. Above this enclosure an electric coil is set to generate a magnetic field. The Brinkman-Forchheimer extended Darcy model is used to solve the momentum equations, and the energy equations for fluid and solid are solved with the local thermal non-equilibrium (LTNE) models. Computations are performed for a range of the Darcy number from \(10^{ - 5}\) to \(10^{ - 1}\), the inclination angle from 0 to \(\pi /2\), and magnetic force parameter \(\gamma\) from 0 to 100. The results show that both the magnetic force and the inclination angle have significant effect on the flow field and heat transfer in porous medium.
