Heat Transfer in a Nanofluid Flow Past a Permeable Continuous Moving Non- Isothermal Surface
Falana, A; Mensah, D. J

This study investigates boundary layer for fluid flow and heat transfer characteristics of an incompressible nanofluid flowing over a permeable non-isothermal surface moving continuously. The local similarity solution is applied to the governing equations. The resulting system of non-linear ordinary differential equations is solved numerically using the Runge-Kutta method with shooting techniques. Numerical results for temperature and concentration distributions, as well as the local Nusselt number Nu and local Sherwood number Sh, have been presented for different values of the governing parameters, such as Prandtl number Pr, temperature exponent, n and the velocity ratio, γ .In particular, it has been found that the heat transfer rate is consistently higher for the lower values of the brownian motion parameter (Nb) but decreases for increase in the thermophoresis parameter (Nt). It is further noticed that the mass transfer rate increases for increase in Nb but decreases for increase in Nt.
