Abstract
Pressure isotherms have been constructed by the molecular dynamics method for nanofluids based on argon and zinc, aluminum, and lithium nanoparticles. Nanoparticle volume concentration is varied from 1 to 10%. Nanoparticles have sizes of 1 or 2 nm. The equation of state has been shown to essentially depend on the volume concentration, size, and material of the particles. Depending on the density of a carrier fluid, the pressure of a nanofluid (at a preset density) may be either higher or lower than the pressure of the basic fluid. On the other hand, the partial pressure of a pseudogas of nanoparticles decreases rapidly with an increase in their sizes (inversely proportional to the cubed particle radius).
