Numerical simulation of magnetohydrodynamic buoyancy-induced flow in a non-isothermally heated square enclosure. (English) Zbl 1221.76155

Summary: Numerical simulation of magnetohydrodynamic (MHD) buoyancy-induced heat transfer and fluid flow has been analyzed in a non-isothermally heated square enclosure using finite volume method. The bottom wall of enclosure were heated and cooled with a sinusoidal function and top wall was cooled isothermally. Vertical walls of the enclosure were adiabatic. Effects of Rayleigh number \((Ra = 10^{4}, 10^{5}\) and \(10^{6})\), Hartman number (\(Ha = 0\), \(50\) and \(100\)) and amplitude of sinusoidal function (\(n = 0.25\), \(0.5\) and \(1\)) on temperature and flow fields were analyzed. It was observed that heat transfer was decreased with increasing Hartmann number and decreasing value of amplitude of sinusoidal function.
