| چکیده | ||
| This present paper reports the effect of thermophoresis and Brownian motion on the electrical magnetohydrodynamic (MHD) two-phase flow of nanofluid towards a linearly stretching sheet. The analysis is offered in cooperation with Joule heating, magnetic field, and chemical reaction. The flow model, represented by a highly nonlinear system of partial differential equations, is converted to dimensionless ordinary differential equations by introducing similarity transformations and then solved computationally using the optimal homotopy analysis method with the Mathematica package BVPh2.0, considering appropriate initial guesses and auxiliary linear operators. Behaviours of various variables affecting the flow, heat and mass transfer, and nanofluid volume fraction are analysed. Skin friction coefficient, local Nusselt number, and local Sherwood number are estimated and studied further. The results show that with increasing values of the thermophoresis parameter, the thermal boundary layer thickness increases near the wall. It is observed that higher values of the Brownian motion parameter tend to increase the fluid temperature profiles. It is also reported that larger values of the electric field parameter increase the local skin-friction coefficient significantly. | ||
