Analysis of Nanofluid Flow with Unequal Diffusivities of H-H Reactions over a Stretching/Shrinking Cylinder

Abstract

The objective is to investigate the outcomes of unequal diffusivities of homogeneous-heterogeneous (H-H) reactions on the nanofluid flowing over a shrinking cylinder. The cylinder is exposed to a perpendicular driven magnetic field. The generalized slip effects will also be studied. Copper-water nanofluid is subject to magnetic field and generalized slip boundary effects in this problem. With the assistance of similarity transformations, the ensuring partial differential equations are modified in dimensionless ordinary differential equation and by the use of shooting technique the resulting numerical solutions will be obtained. The physical effect of all fluid parameters on flow arenas are presented graphically and described in detail with tables. Dual solution is found to exist for shrinking cylinders, while the solution for stretching cylinders is unique. Dual solution is found to exist for shrinking cylinders, while the solution for stretching cylinders is unique. The comparison of the present results with the previous results is presented and found to be in good agreement.
