Investigating the quadratic convective flow attributes of radiative Casson hybrid nanofluid flow across cone and wedge using the Cattaneo-Christov model

Abstract

This study’s main objective is to analyze the nonlinear convective flow behavior (velocity and temperature profiles) of a Casson hybrid nanofluid (HNF) moving close to a wedge and cone embedded in a porous media. A uniformly strong magnetic field is incorporated to the surface of the object, and the Cattaneo-Christov model is used to account the time lag factor in the heating process. When formulating the energy equation in a model, various factors are considered, including dissipation, nonuniform heat source/sink, thermal radiation, and the influence of heating caused by a magnetic field (referred to as Ohmic heating). The bvp4c solver is used to solve the governing equations. Graphs are incorporated to describe the behavior of the relevant factors, and it is demonstrated that when porosity and the magnetic parameter increase, the temperature profile rises in both heat source and sink instances. Also, thermal relaxation and the wall temperature parameter negatively correlate with temperature field. Additionally, the wedge has a superior temperature profile while acting as a heat sink than the cone does when acting as a heat source. This study also revealed that the rate of heat transfer is higher for increasing value of thermal Grashof number and suction parameter for both (cone and wedge) in both the case. On boosting the strength of magnetic parameter and thermal relaxation parameter the value of local skin friction coefficient dwindles.
