Effect of Inclination Angle on Magneto-Convection Inside a Tilted Enclosure

Numerically investigation is carried out for magnetohydrodynamics natural convection in an inclined partitioned enclosure. The vertical walls are maintained isothermal at different temperatures and other walls are adiabatic. Two insulated partitions are located on horizontal walls. Non linear governing equations for the fluid flow and heat transfer are solved for inclination angle varying from 0 deg to 90 deg, three different Hartmann numbers (100, 200, and 300), and three nondimensional partition heights (0.166, 0.25, and 0.33). Rayleigh number and Prandtl number are 10⁶ and 0.054, respectively. A finite volume code based on PATANKAR´s SIMPLER method is utilized. It is found as nondimensional partition height (H_p) and Hartmann number (Ha) increase the mean Nusselt number decreases and this means that the total heat transfer between two isothermal walls is reduced. Also the variation of mean Nusselt number with inclination angle in low Hartmann number is more considerable compare to high Hartmann number.
