Dual Stratification on the Darcy-Forchheimer Flow of a Maxwell Nanofluid over a Stretching Surface

Abstract:

The present study discusses two dimensional Darcy-Forchheimer steady flow of a doubly stratified Maxwell nanofluid over a sheet of continuous stretching. Analysis of thermal energy and species concentration is carried out incorporating radiative heat, thermal and solutal stratifications, Brownian motion and thermophoresis. By introducing suitable transformations the system of equations of the flow are recast into a set of nonlinear ODEs which are then solved numerically by using the RKF-45 method. Flow characteristics are deliberated for different variations of governing parameters. Surface drag force, thermal energy and mass transfer rates are computed and discussed. Favourable comparisons with published work in the literature for different special cases of the problem are examined.
