Abstract: The viscosity of nanofluids is studied by molecular dynamics method. It is considered the model nanofluids based on liquid argon with aluminum and lithium nanoparticles. The nanoparticle size ranges from 1 to 4 nm. The volume concentration of nanoparticles is varied from 1% to 12%. It is shown that the viscosity of the nanofluid increases with decreasing nanoparticle size. Potential contribution to viscosity of nanofluid considerably exceeds the kinetic one. Therefore parameters of molecule-molecule and nanoparticle-molecule potentials make the considerable impact on viscosity of nanofluids which, thus, depends on material of nanoparticles.
