Three-dimensional flow of an elastico-viscous nanofluid with chemical reaction and magnetic field effects

Abstract

Magnetohydrodynamic (MHD) three-dimensional flow of an elastico-viscous nanofluid under the influence of mass transfer and chemical reaction is studied. The flow is produced by a bidirectional stretching sheet. Effects of thermophoresis and Brownian motion are also present. In the presence of constant applied magnetic field, the fluid is electrically conducting. Using appropriate transformations, the governing nonlinear partial differential equations are converted into highly nonlinear coupled ordinary differential equations. Homotopy Analysis method (HAM) is employed to find the series solution of the acquired system of equations. h-curves have been drawn to discuss the convergence of HAM solution. Effects of velocity, temperature and concentration profiles on the emerging important parameters is portrayed and discussed graphically. Numerical values of local Nusselt number, skin friction and Sherwood number with different parameters are calculated and examined. It is observed that temperature profile increases and concentration profile decreases with increasing values of Brownian motion parameter Nb. It is also noticed that both velocity components decrease with an increase in viscoelastic parameter k.
