Inspections of unsteady micropolar nanofluid model over exponentially stretching curved surface with chemical reaction

Abstract

The present study considers heat transfer analysis of micropolar nanofluid flow over an exponentially stretching curved surface. The effects of Brownian motion and thermophoresis on the micropolar fluid at exponentially stretching curved surfaces are considered. The chemical reaction and slip effects are analyzed at exponentially stretching curved surface. Using boundary layer approximations, the mathematical model under the flow assumptions is developed in partial differential equations. The partial differential equations are transformed into ordinary differential equations using the dimensionless similarity variables. The dimensionless system is solved through numerical technique. The involving physical parameter effects are presented through graphs and tables. The is enhanced due to rising the values of the curvature parameter. If the curvature is increasing, the bending of the sheet is more which enhances the motion of the fluid particles due to the action of centrifugal force. The Schmidt number enhances which reduces the concentration profile because is directly proportional to the momentum diffusivity and inversely proportional to the mass diffusivity, and consequently, greater the values of conformed to the small mass diffusivity which declines the concentration function.
