Oblique stagnation point flow of magnetized Maxwell fluid over a stretchable Riga plate with Cattaneo-Christov heat flux and convective conditions

Abstract

Abstract The main intension of the current work is to scrutinize the oblique stagnation point flow phenomenon of a rate-type non-Newtonian Maxwell fluid with the involvement of the Cattaneo-Christov double diffusion theory. The modified form of Fourier’s and Fick’s laws is utilized to illustrate the Cattaneo-Christov theory. The steady magnetized flow mechanism is observed in two dimensions through a stretchable convective Riga plate. In the heat and mass transfer analysis, the consequences of chemical reactions and thermal radiation are also incorporated. With the contribution of relevant dimensionless quantities, the setup of dimensionless equations is acquired which further takes the form of nonlinear equations. The physical significance of the numerous parameters on different features of the flow phenomenon is graphically exhibited. The physical quantities of interest are computed and numerically evaluated subject to the pertinent parameters. The current analysis exhibit that the Deborah number minimizes the flow field of both tangential and axial velocities. The thermal relaxation time parameter lowers the heat transfer rate, and the thermal Biot number enhances the rate of heat transport.
