Spherical shaped (Ag-Fe 3 O 4 /H 2 O) hybrid nanofluid flow squeezed between two riga plates with nonlinear thermal radiation and chemical reaction effects

Abstract

The main concern is to explore an electro-magneto hydrodynamic (EMHD) squeezing flow of (Ag-Fe 3 O 4 /H 2 O) hybrid nanofluid between stretchable parallel Riga plates. The benefits of the use of hybrid nanofluids, and the parameters associated to it, have been analyzed mathematically. This particular problem has a lot of importance in several branches of engineering and industry. Heat and mass transfer along with nonlinear thermal radiation and chemical reaction effects have also been incorporated while carrying out the study. An appropriate selection of dimensionless variables have enabled us to develop a mathematical model for the present flow situation. The resulting mathematical method have been solved by a numerical scheme named as the method of moment. The accuracy of the scheme has been ensured by comparing the present result to some already existing results of the same problem, but for a limited case. To back our results further we have also obtained the solution by anther recipe known as the Runge-Kutta-Fehlberg method combined with the shooting technique. The error analysis in a tabulated form have also been presented to validate the acquired results. Furthermore, with the graphical assistance, the variation in the behavior of the velocity, temperature and concentration profile have been inspected under the action of various ingrained parameters. The expressions for skin friction coefficient, local Nusselt number and local Sherwood number, in case of (Ag Fe3O4/H2O) hybrid nanofluid, have been derived and the influence of various parameters have also been discussed.
