The influence of MHD and heat generation/absorption in a Newtonian flow field manifested with a Cattaneo–Christov heat flux model

Abstract

The purpose of this report is to emphasize magnetohydrodnamics, heat generation/absorption and slip effects over a Newtonian fluid flow with homogeneous–heterogeneous chemical reactions induced by the rotating disk. The homogeneous reaction is provided by isothermal cubic autocatalytic kinetics and the heterogeneous reaction by first order kinetics. The concerned steady state boundary layer flow is discussed in the case when both reactants and auto-catalyst have equal diffusion coefficients. The Cattaneo–Christov approach is proposed to derive the energy equation and heat transfer phenomena. The consequential partial differential equations descend to ordinary differential equations by using similarity transformation. Further, these equations are sorted numerically using the Runge–Kutta–Fehlberg technique with a shooting scheme. The influences of arising parameters on fluid velocity, temperature and concentration are observed through graphs. Further, the numerical results for the skin friction coefficient and local Nusselt number are examined and compared with existing literature.
