A two-dimensional (2D) flow of an incompressible Williamson fluid of Cattaneo-Christov heat flux type over a linearly stretched surface with the influence of magnetic field, thermal radiation-diffusion, heat generation and viscous dissipation is carried out in the present study. To develop a Williamson flow model, a boundary layer approximation is taken into account. The non-dimensional, nonlinear, coupled ordinary differential equations with boundary condition are solved numerically using Nactsheim-Swigert shooting iteration technique together with Runge-Kutta six order iteration scheme. The influences of physical parameters on the velocity, temperature, concentration is analysed through graphical consequences. To validate the accuracy of the numerical simulations scheme, comparisons is carried out with the previous studies and are found in an excellent agreement.

“…Transfer of heat from a flow between stretchable coaxial spinning disks in a thermally stratified medium was studied by Hayat et al [2] with conclusions that radial and axial velocities decrease towards the lower disk by enhancing Reynolds number and that tangential velocity is a decreasing function of magnetic number. Diffusion-thermo and thermal diffussion effects on MHD flow of a viscous liquid between enlarging/contracting rotary disks with viscous dissipation were investigated by Srinivas et al [3]. They deduced that the flow temperature increases while the concentration decreases with increment in Soret and Dufour parameters.…”

This paper examines the transport of a chemically reacting nanofluid in a porous medium between two rotary disks with Cattaneo-Christov?s heat flux. The non-linear ordinary differential system formed under Vonn Karman transformation of a non-linear partial differential system is solved via a shooting method with MATLAB bvp4c. The nanofluid thermodynamics profiles with variation in physical properties of thermal relaxation time, thermal radiation, porosity, and chemical reaction are observed. Axial, radial, and tangential velocities are found to be increasing functions of porous medium. A decrease in the fluid temperature is perceived as thermal radiation and thermal relaxation increase since more heat can be transported to neighboring surroundings. The concentration is enhanced with intensified Cattaneo-Christov?s thermal relaxation but it oscillates with reacting chemicals. The rotary disks bound the oscillating nanofluid from downward to up-ward directions and vice versa. The axial velocity represents the change in force due to porosity and radial stretching of the disks.

“…Zhao et al have concerned an unsteady 2D natural convection MHD Maxwell fluid flow over a vertical plate under the influence of Dufour and Soret effects. Srinivas et al have analyzed the unsteady 3D MHD viscous fluid flow confined between contracting or expanding rotating porous walls with Dufour and Soret effects. Khan et al had examined purely radial and symmetric chemically reacting viscous fluid flow in converging and diverging channel with diffusion‐thermo and thermal‐diffusion effects and obtained an analytical solution by Adomian decomposition method (ADM).…”

The present communication deals the entropy generation by cause of heat and mass transform in an unsteady mixed convective radiative squeezing flow of a Casson fluid confined between two parallel disks in the presence of diffusion‐thermo and thermal‐diffusion effects and temperature jump. The lower disk is taken to be porous and the upper one is impermeable. The governing PDE is converted as nonlinear ordinary differential equations (ODE) by using well‐established similarity transformations; then, the reduced nonlinear ODE are solved by shooting method with Runge‐Kutta fourth‐order approach. The influence of distinct nondimensional fluid and geometric‐related parameters on the velocity profiles, temperature, concentration, entropy generation number, and Bejan number are studied in detail and represented in the form of graphs. The entropy of the Casson fluid is increased with the Eckert number, whereas the concentration profile is decreased by squeezing Reynolds number. The current results are correlated with existing results for the viscous case and found to be in better agreement.
