Abstract

The steady state, viscous flow and heat transfer of a nanofluid in the vicinity of an axisymmetric stagnation point of a stationary cylinder is investigated. Exact solution of the Navier–Stokes equations and energy equation are derived in this problem. For all Reynolds numbers, as the particle fraction increases, the depth of diffusion of the thermal boundary layer and shear stresses decreases. It’s clear that by adding nanoparticles to the base fluid there is a significant enhancement in convective heat transfer coefficient and convective heat flux.
