Heat And Mass Transfer In Non-Newtoniannanofluid Flow From A Vertical Melting Front
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
In present work, the problem of convective boundary layer flow of a warm laminar nonNewtonian nanofluid over a vertical surface with melting effect is studied numerically. A non-Newtonian fluid is one whose stream bend is nonlinear. The relationship between shear stress and shear rate for this type of fluid can be mathematically expressed as τyx = K(γ yx ) n , so the apparent viscosity for the power law fluid is μ = K(γ yx ) n−1 . The fluid display diverse properties, shear-thinning, Newtonian behaviour, shear thickening for different values of power law index. A nanofluid model is employed to incorporate the effects of brownian motion and thermophoresis. The governing set of partial differential equations was non-dimensionalized and reduced to a set of ordinary differential equations and is then solved numerically using Matlab. Numerical results for surface heat transfer rate and mass transfer rate are studied in the presence of different physical parameters and are presented graphically.
