RBF-FD Solution of Natural Convection Flow of a Nanofluid in a Right Isosceles Triangle Under the Effect of Inclined Periodic Magnetic Field

Abstract

In this study, numerical simulation of natural convection flow of Cu-water nanofluid flow in a right triangular cavity under the influence of an inclined periodic magnetic field is conducted. Two-dimensional and steady dimensionless governing equations are considered in stream function-vorticity form. Radial basis function based finite difference (RBF-FD) method augmented with polynomial terms is utilized. The pertinent parameters Hartmann number, inclination angle and period of magnetic field are observed in numerical results. Horizontal periodic magnetic field coming through the vertical left wall having a heater suppresses fluid flow and heat transfer significantly comparing to other inclination angles of magnetic field. In this situation of magnetic field, period one also has more inhibitive effect than the periods less than one.
