A numerical study of heat and mass transfer characteristic of three-dimensional bi- directional permeable stretching surface with thermal radiation, chemical reaction, and slip boundary conditions

Abstract

Heat and mass transport characteristics of hybrid nanofluid magnetohydrodynamic (MHD) flow with chemical reaction, thermal radiation and slip effects over a stretching surface is scrutinized in this study. The nanoparticles copper and alumina are combined with water for the formation of hybrid nanofluid. Using the self-similar method for the transformation of governing flow equation PDEs to the system of ODEs which are nonlinear. Along with boundary conditions, these systems of equations is solved numerically utilizing bvp4c technique. The effect of the different physical non-dimensional flow parameters on different flow profiles such as velocity, temperature and concentration are depicted through graphs. The numerical outcomes of skin friction, Nusselt number, and mass transfer rate for various prominent parameters are shown in Tables. The velocity profiles diminish with the effect of magnetic and slip parameters. The velocity along y direction shows direct link with the ratio parameter while velocity along x direction shows opposite impact. Both the temperature and concentration slip parameters leads to reduce the temperature and concentration profile respectively also the Nusselt and Sherwood numbers. The thermophoresis and Brownian motion enhance the Sherwood number while decreasing the Nusselt number. Comparison is made between the already published work to the present and found excellent agreement between them.
