SCRUTINIZING THE INFLUENCE OF MULTIPLE SLIP EFFECTS ON THE MHD EYRING-POWELL NANOFLUID FLOW FLOWING OVER THIN NEEDLE
Arindam Das, Dr. Annapurna Ramakrishna Sinde, Dr. Md Tausif Sk
Abstract
MHD boundary layer flow of Eyring – Powell nanofluid over a thin needle is analyzed here. We applied first order velocity slip; temperature slip and nanoparticle concentration slip conditions at the boundary of the flow. To construct the flow model, we considered the Brownian motion and thermophoresis phenomenon in the nanoscale level. Then using dimensionless similarity transformations, we transform the set of PDEs into suit of ODEs along with suitable boundary conditions. We solve the model by using Runge – Kutta Fehlberg scheme (RKF45) in the Maple 17 software. The results are staged on form of graphs and charts. The results are compared in two different scenarios like no magnetic force field and applied magnetics force field.
