Краткое описание

This work investigates the magnetohydrodynamic boundary layer flow of Sisko nanofluid flow over a wedge. Our nanofluid model incorporates the influences of thermophoresis and Brownian motion. Using a suitable similarity transformation, the governing nonlinear partial differential equations for the modelling of boundary layer flow are reduced to coupled nonlinear ordinary differential equation. The resulting ordinary differential equations are success-fully solved numerically with the help of the variational finite element method. To validate the present investigation, the obtained numerical results are compared to available results in the literature for some special cases and found to be in good agreement. The effects of the flow-controlling parameters on velocity, temperature, and nanoparticle volume fraction profiles are investigated through graphs. Numerical results of the local skin-friction coefficient and local Nusselt number are presented for several sets of values of physical parameters, and the salient features are discussed in detail. With the rise of the thermophoresis parameter, both the fluid temperature and nanoparticle volume fraction increase. It is found that the nanoparticle volume fraction decreases as the Brownian motion increases. Increasing Sisko fluid parameter decreases the velocity profiles whereas increases the temperature and nanoparticle volume fraction profiles.
