Dynamics of lorentz force and cross-diffusion effects on ethylene glycol based hybrid nanofluid flow amidst two parallel plates with variable electrical conductivity: A multiple linear regression analysis

Abstract

This research investigates how the presence of Dufour and Soret parameters affect the properties of hybrid nanofluid flow amidst two parallel plates with temperature dependent electrical conductivity. Heat transport procedure is studied using thermal radiation parameter and Eckert number. Equations that characterize the current problem are turned into a set of ordinary differential equations, which are then solved with the assistance of a built-in function in MATLAB called the bvp4c solver. Multiple linear regression is used to explain physical parameters of interest including Sherwood number. The main conclusions of this study are that the velocity decreases with increasing nanoparticle volume fraction parameter and the concentration profile minifies with the rise in Soret parameter. It is observed that the increase in Dufour number causes a corresponding increase in the fluid temperature. It is discovered that, when the magnetic field parameter (M) is set to 0≤M≤2.5, the decreasing rate in the skin friction parameter is 0.02215. It is observed that, when φ1 is set to 0≤φ1≤0.25, Nusselt number drops by 3.82891. It is detected that, when Sr is set to 0≤Sr≤2.5, Sherwood number increases at a rate of 0.037225.
