Numerical Simulation for Buoyancy Induced Natural Convection of (Ag- MgO/H 2 O) Hybrid Nanofluid in a Horizontal Corrugated Cavity

Abstract

Abstract This work scrutinizes the influence of nanoparticles volume fraction and Rayleigh number on hybrid nanofluid flow and heat transfer in a corrugated closed chamber. By using a non-dimensional parameter, partial differential equations that are dimensional are reduced to dimensionless differential equations. Obtained equations are attempted by applying finite element method (FEM) and solution is compared with work in literature and discovered an excellent match. Heat transfer is minimized by the increasing Rayleigh number while heat transport was influenced by the volume fraction values of nanoparticles. Horizontal and vertical velocities shows the sinusoidal behaviour for Ra and \(\varphi\)values. Nusselt number for upper rectangular bars are increasing for Rayleigh number values and Nusselt number for corrugated side walls showed no significant effect.
