Abstract
The turbulent forced convection of nanofluids with ZrO2 nanoparticles in a channel with artificial roughness was experimentally and numerically investigated. Nanoparticle concentration in the experiments was equal to 4 vol. %. The nanoparticle size ranged from 44 to 105 nm. Numerical simulation of turbulent forced convection of nanofluids in a channel with annular knurls was carried out. A homogeneous model with experimentally determined transport coefficients was used to describe the nanofluid.
