## Boundary-layer flow of a nanofluid past a stretching sheet.(English)Zbl 1190.80017

Summary: The problem of laminar fluid flow which results from the stretching of a flat surface in a nanofluid has been investigated numerically. This is the first paper on stretching sheet in nanofluids. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis. A similarity solution is presented which depends on the Prandtl number $$Pr$$, Lewis number $$Le$$, Brownian motion number $$Nb$$ and thermophoresis number $$Nt$$. The variation of the reduced Nusselt and reduced Sherwood numbers with $$Nb$$ and $$Nt$$ for various values of $$Pr$$ and $$Le$$ is presented in tabular and graphical forms. It was found that the reduced Nusselt number is a decreasing function of each dimensionless number, while the reduced Sherwood number is an increasing function of higher $$Pr$$ and a decreasing function of lower $$Pr$$ number for each $$Le, Nb$$ and $$Nt$$ numbers.
