ABSTRAKT

In the present study, a heat and mass transfer analysis for boundary layer flow over a stretching cylinder in a medium saturated with a nanofluid is investigated numerically. The model used for the nanofluid comprises the effects of Brownian motion and thermophoresis parameters, which are the most important parameters in nanofluid simulations. A similarity solution is presented that depends on the Prandtl number, Reynolds number, Lewis number, Brownian motion, and the thermophoresis parameter. The results of the present paper show that the reduced Nusselt and reduced Sherwood numbers increase with the Reynolds number. Also, the reduced Nusselt number decreases as the Brownian motion and thermophoresis parameters increase.
