Abstract: A numerical study of three dimensional magnetohydrodynamic flow of nanofluid over a surface stretching linearly in two directions is carried out. The problem is analysed from first and second law of thermodynamics point of view. Suitable similarity transformations are employed to obtain nonlinear ordinary differential equations from the partial differential equations that govern the considered problem. The shooting technique with fourth fifth order Runge Kutta method is utilised to solve the converted equations. The effects of pertinent parameters on velocity and temperature profiles as well as on entropy generation are discussed briefly using graphs.
Keywords: Buongiorno model; Brownian motion; thermophoresis; entropy generation; magnetic field.
