Abstract
•MHD flow of Newtonian liquid towards a stretched Riga device is addressed.•Cattaneo-Christov (CC) heat and mass flux models are utilized instead of Fourier and Fick's heat and mass flux.•Binary chemical reaction and activation energy are further considered.•Analytical solutions are obtained through homotopy analysis technique.
Background Current paper elaborate the impact of MHD flow of Newtonian liquid over a extendable Riga sheet. Cattaneo-Christov (CC) heat and mass flux models in formulation are taken here. Fluid filling porous medium is considered. Influences of activation energy is also considered. Boundary layer approximation is used in obtaining partial differential equations (PDEs). Applying suitable transformation to reduce the given PDEs into ordinary differential (ODEs) system.
Method Homotopy method is utilized to solve non-linear differential system.
Results The impacts of influencing parameters like modified Hartman number, mixed convection parameter, inverse Darcy parameter, non-dimensional parameter, Biot number, non-dimensional activation energy, Eckert number, thermal relaxation and solutal concentration variables are examined through graphs.
Conclusions Velocity profile enhances for larger estimation of ratio parameter and modified Hartman number. Temperature distribution is higher for Eckert and Biot number. Concentration profile is enhancing for more values of nondimensional activation energy.
