Numerical Analysis of Suction/Blowing on MHD Viscousnanofluid Flow over Stretched Surface with Velocity and Thermal Slip Conditions

Abstract

This paper studied the effects of suction/blowing parameters of magnetohydrodynamic (MHD) nanofluid’s viscous flow over an exponentially stretching sheet. In this work, nanofluid flow of water-based copper was considered as a nanoparticle. The radiation parameters, velocity and thermal slip constraint, and magnetic field were applied in similarity transformations to solve the nonlinear ordinary differential equations (ODEs) approximately by reducing the nonlinear partial differential equations (PDEs). The obtained numerical results of velocity and temperature against different values of suction/blowing parameters with varying profiles were displayed and analyzed by using Maple 18 software based on the fourth-fifth order Runge-Kutta Fehlberg technique with shooting method. The dimensionless Velocity decreased with the increasing magnetic field, suction/blowing, and thermal slip condition parameters. Whereas, the profiles of temperature intensified with the growing magnetic field, velocity slip and thermal radiation parameters. Finally, in the experiment, the effect of increased velocity and thermal slip parameters in general caused decrease in the heat transfer with base fluid, but in case of nanofluid this impact was lesser. Alternatively, it can be stated that the effect of suction/blowing parameter caused a decrease and then an increase in the heat transfer.
