Nanofluid Film Flow of Eyring Powell Fluid with Magneto Hydrodynamic Effect on Unsteady Porous Stretching Sheet

摘要

This article investigates two dimensional nanofluid film flowof Eyring Powell Fluid with variable heat transmission in the existence ofuniform magnetic field (MHD) on an unsteady porous stretching sheet.Thebasic governing time dependent equations of momentum, heat transfer andmass transfer are modeled and reduced to a system of differential equationsby employing appropriate similarity transformation with unsteadydimensionless parameters.The important influence of thermophoresis andBrownian motion have been taken in the nanofluids model.An optimal approachhas been applied to get appropriate results from the modeled problem.The convergence of HAM (Homotopy Analysis Method) has beenidentified numerically.The discrepancy of the Nusslet number, skin friction,Sherwood number and their influence on the velocity, temperatureand concentration profiles has been scrutinized.The influence of the unsteadyparameter (A) over thin film is explored analytically for differentvalues.Moreover, for comprehension the physical presentation of the embeddedparameters like Film Thickness parameter ( ), Magnetic parameter(M), Stretching parameter (), and Eyring Powell fluid parameters (k)have been plotted graphically and discussed.Prandtl number (Pr), Brownianmotion parameter (Nb), Thermophoretic parameter (Nt), Schmidthnumber (Sc) have been represented by graph and discussed.
