Abstract In the present study, the flow and heat transfer characteristics of a nanofluid in an expanding or contracting porous channel with different
permeabilities in presence of thermal radiation are investigated. Analytical solutions for the flow variables are obtained by employing homotopy
analysis method (HAM). Maxwell-Garnetts and Brinkman models are considered to calculate the thermal conductivity and the viscosity of
nanofluid. In this investigation, we considered water and ethylene glycol as base fluids and silver (
Ag
), copper (
Cu
), titanium dioxide (
TiO2
) and
alumina (
Al2O3
) as nanoparticles. The effects of various More >
