CUMULATIVE IMPACT OF VISCOUS DISSIPATION AND HEAT GENERATION ON MHD DARCY-FORCHHEIMER FLOW BETWEEN TWO STRETCHABLE DISKS: QUASI LINEARIZATION TECHNIQUE

Abstract

This research describes the irreversibility analysis of steady flow with magnetic effects between two infinite stretching disks situated in a Darcy-Forchheimer medium. The energy equation is amended by the features of thermal radiation and heat absorption or generation. Similarity transformations are employed to transform the formulated equations into dimensionless form. Quasi linearization technique with the application of mathematical computational software MATLAB is used to acquire the numerical solution of these non-dimensional modeled equations. It is noticed that Eckert number, heat generation/absorption and Forchheimer parameter accelerate the temperature, while the radiation parameter decreases the temperature. It can also be observed that axial velocity is affected by inertia as well as porosity of the medium. Moreover, skin friction coefficient is an escalating function of porosity, magnetic and Forchheimer parameters.
