Abstract

The laminar fully developed nanofluid flow and heat transfer in a horizonal channel are investigated. Highly accurate solutions for the temperature and nanoparticle concentration distributions are obtained. The effects of the Brownian motion parameter Nb, the thermophoresis parameter Nt, and the Lewis number Le on the temperature and nanoparticle concentration distributions are discussed. The current analysis shows that the nanoparticles can improve the heat transfer characteristics significantly for this flow problem.

Key words： homotopy analysis method (HAM); static thermoelastic contact; nonmonotone multivalued friction; hemivariational inequality; substationary problem; finite element approximation; nanofluid flow; mixed convection heat transfer; horizontal channel
