摘要

Due to its industrial applications in last 2decades, in this study, the second law of thermodynamics is applied to MHD flow of water-based nanofluids past a static wedge. The Buongiorno model with Navier slip and convective boundary conditions is employed; in addition, the effects of Brownian motion and thermophoresis have been included. An attempt has been made to focus on the effects of magnetic field, Navier slip and convective heat of nanofluid flow over a wedge. Using similarity transformations, the governing partial differential equations are reduced to ordinary differential equations which are solved by using the spectral quasi-linearization method. The numerical solution for the dimensionless temperature, velocity and concentration gradients is performed to investigate the variation of dimensionless entropy generation due to fluid flow, thermal gradient, mass and combined impact of heat and mass transfer past a static wedge. The effects of magnetic field, Navier slip, convective heat and mass boundary conditions on the forced convection of nanofluid over a wedge are investigated. Original results observed show that the total dimensionless entropy generation rate increases significantly with local Reynolds number, Prandtl number and thermophoresis parameters.
