MHD Natural Convection and Radiation over a Flame in a Partially Heated Semicircular Cavity Filled with a Nanofluid

The numerical analysis of MHD-free convective heat transfer and its interaction with the radiation over a heated flame inside porous semicircular cavity loaded SWCNTs–water nanofluid was explored for very first time in present work. two circular arcs upper wall enclosure were preserved at constant cold temperature, whereas middle region it considered adiabatic. midland lower partially, while other regions also assumed An internal hot included cavity, exposed to magnetic field. results illustrated Hartmann number (0 ? Ha 100), Rayleigh (104 Ra 106), length (0.1 L 0.3), solid volumetric fraction ? 0.04), Darcy (10?3 Da 10?5) parameter Rd 1). It found that decreasing is best option enhancing natural convection. Moreover, noted (Nuout) directly proportion (Ra), (?), (Rd) (Da) increase. In contrast, reverse (Ha). Furthermore, showed augmentation about (4%) decrement (56.55%) are obtained on average (Nu) by increasing number, respectively. raising from 1) causes an (73%) flame. Results indicated will cause (82.4%) maximum velocity profile vertical direction.
