Heat transfer of nonlinear radiative magnetohydrodynamic Cu-water nanofluid flow over two different geometries

Abstract

The knowledge of heat transfer of MHD nanofluid flows over different geometries is very important for heat exchangers design, transpiration, fiber coating, etc. With this initiation, mathematical model is developed to investigate the heat transfer nature of electrically conducting magnetohydrodynamic nanofluid flow over a cone and a wedge. For this investigation, we consider a nonlinear thermal radiation, viscous dissipation, Joule heating with non-uniform heat source/sink effects. Water considered as the base fluid and suspended with copper nanoparticles. R-K and Newton's methods are employed to resolve the altered governing nonlinear equations. Effects of pertinent parameters of concern on the common profiles are conversed (in two cases). It is observed that the momentum and temperature boundary layers are non-uniform for the flow over three a wedge and a cone. Rising the viscous dissipation strengths the velocity and temperature fields.
