MHD Radiative Flow of Williamson Nanofluid With Cattaneo-Christov Model Over a Stretching Sheet Through a Porous Medium in the Presence of Chemical Reaction and Suction/Injection

The purpose of this study is to investigate the heat and mass transfer of MHD Williamson nanofluid in a porous medium with Cattaneo-Christov double diffusion on a stretching surface. Also, we studied the influence of radiation, chemical reaction, heat generation and suction/injection effects on the present flow. The mathematical model (PDEs) transformed into nonlinear coupled ODEs with the help of appropriate transformations. The numerical solution of the system of simplified differential equations was obtained through the bvp5c MATLAB package. The behavior of various parameters on the flow regime is examined and presented through graphs and tables. It is concluded that an enhancement in the magnetic field, porosity parameter and suction parameter declines the velocity field. Moreover, the rate of heat transfer enhances with an increase in thermal radiation, whereas it declines with the rising values of Brownian motion, thermophoresis, heat generation, thermal relaxation time and concentration relaxation time. The validation of the present results is carried out with the existing literature and noted a good agreement.
