摘要：
The aim of the present paper is to study the Cu-water nanofluid flow and heat transfer characteristics of a stretching permeable cylinder. Thermal radiation effect is considered in energy equation. The governing partial differential equations with the corresponding boundary conditions are reduced to a set of ordinary differential equations with the appropriate boundary conditions using similarity transformation, which is then solved numerically by the fourth order Runge-Kutta integration scheme featuring a shooting technique. Numerical results for the flow and heat transfer characteristics are obtained for various values of the nanoparticle volume fraction, suction parameter, Reynolds number and radiation parameter. The results show that skin friction coefficient increases with increase of Reynolds number and suction parameter but it decreases with increase of nanoparticle volume fraction. Nusselt number is an increasing function of nanoparticle volume fraction, Reynolds number and suction parameter but it is a decreasing function of radiation parameter.
