A hydrodynamic and hydromagnetic comparative analysis of triple diffusive nanofluid flow over a horizontal plate with quadratic mixed convection

Abstract

The triple diffusion amalgamated with the convection occurs when the fluid flow is under the influence of two different densities with varied diffusion rates. The primary objective of this analysis is to compare hydrodynamic and hydromagnetic nanofluid flow over a horizontally placed plate for triple diffusive systems with mixed convection of quadratic nature. The additional novel features of the envisaged model are the consideration of variable thermal conductivity and nonlinear thermal radiative heat flux. The problem is comprised of a set of equations that are solved with the aid of the MATLAB bvp4c package. To visualize the impacts of the parameters with associated profiles, graphical illustrations are given. Graphs are utilized to evaluate how significant changes in the key parameters impact the related fields and their corresponding physical quantities. It is inferred that liquid velocity surges for numerous estimates of the Dufour parameter of salt 1 and salt 2. It is verified that the hydrodynamic flow is dominant in comparison to hydromagnetic. In addition, a comparison between the published results in a specific scenario and the current research is also included. An excellent correlation is attained.
