Mixed kinetic-hydrodynamic level of description for dispersed liquids

It is shown that dispersed liquids (gaseous or liquid suspensions) can only be described at the hydrodynamic level over a limited range of flow parameters. A mixed kinetic-hydrodynamic model is proposed to describe flows of dispersed liquids.     

On the thermal conductivity of nanofluids

The dependence of the effective thermal conductivity λ of nanofluids on the properties of dispersed nanoparticles has been studied by the molecular dynamics method. It is established that the thermal conductivity of a nanofluid always exceeds that of the carrier medium, the excess depending on the volume fraction of nanoparticles, their masses, and sizes. An increase in the nanoparticle mass at a constant size leads to a more pronounced increase in λ than does the growth in size at a constant mass, which implies that the density of dispersed nanoparticles is an important factor that determines the thermal conductivity of nanofluids.
