Boundary Layer Flow Of Nanofluid Past An Inclined Stretching Sheet

Author(s) : JULIE ANDREWS

Abstract

Nanofluids, in which nano-sized particles (typically less than 100 nanometers) suspended in liquids, have emerged as a potential candidate for the design of heat transfer fluids. The main goal of nanofluids is to achieve the highest possible thermal properties at the smallest possible concentrations by uniform dispersion and stable suspension of nanoparticles in host fluids. This paper also includes diverse applications of nanofluids. Along with the cooling applications, there are tribological and medical applications for nanofluids. Nanofluids could be utilized for a wide variety of applications in day today life. The problem of laminar fluid flow which results from an inclined stretching flat surface in nanofluid has been investigated numerically in this paper. The model used here for the considers the effects of Brownian motion and thermophoresis. A similarity solution is presented which depends on the Prandtl number Pr, Lewis number Le, Brownian number Nb and thermophoresis number Nt. The coupled partial differential equations governing the flow are transformed into nonlinear boundary layer equations, which are then solved using the Nachtsheim-Swigert Shooting iteration technique along with the fourth order Runga Kutta method. The variation of the Nusselt and Sherwood numbers with Nb ,Nt ,Pr , Le,Gr and Gc for various values of angle of inclinations α is presented in graphical forms.
