Radiation, Dufour, Magnetohydrodynamic and Double Dispersion Influence Over a Nanofluid Flow with Scaling Group Analysis on a Wedge

Abstract

Mixed convection in nanofluids for varying geometries like the vertical sheets, exponentially stretching sheets etc. contributes to various fields of science and technology applicable to nature and natural processes. Based on the wide range of applications of thermal radiation, double dispersion and magnetohydrodynamic (MHD) flows in the engineering fields, our study focuses on their combined effects on the mixed convection flow over a vertical wedge which has not been studied earlier. Non-dimensional variables have been introduced with scaling group applications for converting the governing set of partial differential equations to a new set of ordinary differential equations by the help of similarity transformations. Shooting method with bvp4c routine has been used to formulate the equations numerically. Among all the parameters discussed, λ and Peζ exposes an augmentation in the heat transfer while a decrement in the mass transfer coefficient, which is a reverse trend to the other parameters involved. Nusselt number decreases for the incrementing magnetic parameter while an augmenting Sherwood number is noticeable. The originality of the current work is to motivate the researchers and emphasize on the awareness of the influences on flow behavior and heat and mass transfer of the nanofluid flow over the vertical wedge geometry.
