文摘

Nanoparticles diffusion terms and other slip mechanisms were implemented for convective nanofluids. The simulation heat transfer results of the new approach were found in good agreement with experimental measurements. The nanoparticle concentration distribution inside the boundary layer is highly affected by the diffusion terms. The electrostatic forces can compete with bouncy force at the bottom of the cavity by increasing the volume fraction.
