Abstract

This study deals the simultaneous effects of inclined magnetic field and prescribed surface temperature (PST) on boundary layer flow of nanofluid over a stretching sheet. In order to make this mechanism more feasible, we have further considered the velocity slip and thermal radiation effects. Moreover, this perusal is made to consider the two kinds of nanofluid namely: Cu-water and Al2O3-water. Inclined magnetic field is utilized to accompanying an aligned angle that varies from 0 to π/2. The exact solutions are acquired from the transformed non-dimensional momentum and energy equations in the form of confluent hypergeometric function. Lorentz forces and aligned magnetic field depicts the significant effects on nanofluid. We found that, due to the increase in the aligned angle provides the enhancement in local skin friction coefficient and a reduction in the local Nusselt number. The combined impacts of inclined magnetic field with other emerging parameters such as velocity slip, thermal radiation and nanoparticles volume fraction on velocity, temperature, local Nusselt number and skin friction coefficient are examined. Flow behavior of nanofluid is also determined via stream lines pattern.
