要約

This paper examines the influence of uniform magnetic field on mixed convection flow in a rectangular enclosure filled with fluid saturated porous medium with the presence of internal heat generation and is subjected to nonuniform heating. The enclosure model has a mid-horizontal moving plate, adiabatic top and bottom walls, and sinusoidally varying vertical walls. The governing equations and boundary conditions are discretized using the finite volume approach with power law scheme and solved numerically by the SIMPLE algorithm for the pressure-velocity coupling together with the under-relaxation technique. Results are found for the various dimensionless governing parameters, such as Hartmann number, Richardson number, Darcy number, phase deviation, heat generation parameter, and amplitude ratio. Especially, some particular values of Hartmann number show significant influence on the flow structure, heat distribution, velocity fields, and heat transfer rate within the enclosure.
