Stratified magnetohydrodynamic flow of tangent hyperbolic nanofluid induced by inclined sheet

doi:10.1007/s10483-017-2168-9

Abstract

Abstract:

This paper studies stratified magnetohydrodynamic(MHD) flow of tangent hyperbolic nanofluid past an inclined exponentially stretching surface. The flow is subjected to velocity, thermal, and solutal boundary conditions. The partial differential systems are reduced to ordinary differential systems using appropriate transformations. The reduced systems are solved for convergent series solutions. The velocity, temperature, and concentration fields are discussed for different physical parameters. The results indicate that the temperature and the thermal boundary layer thickness increase noticeably for large values of Brownian motion and thermophoresis effects. It is also observed that the buoyancy parameter strengthens the velocity field, showing a decreasing behavior of temperature and nanoparticle volume fraction profiles.

Key words: double stratification, tangent hyperbolic nanofluid, two-dimensional magnetohydrodynamic(MHD) flow, exponential stretching, inclined sheet, mixed convection
