EQUATION OF STATE AND PHASE BEHAVIOR OF WORKING NANOFLUIDS
Abstract
The importance of thermodynamic and phase behavior of working fluids embedded with nanostructured
materials is fundamental to new nanotechnology applications. Considering the extremely large number of
different both nanoparticle types and reference fluids, it is obvious that there is need for developing theoretically
sound methods of the prompt estimation thermodynamic properties and phase equlibria for emerging working
media. The effect of nanoparticles on the critical point shift for classical fluids doped by nanoparticles is
examined. Global phase diagrams of two-component fluids with nanoparticles are analyzed. The global phase
diagram studies of binary mixtures provide some basic ideas of how the required methods can be developed to
visualize the phase behavior of nanofluid blends. The mapping of the global equilibrium surface in the parameter
space of the equation of state (EoS) model provides the most comprehensive criteria for predicting binary
nanofluid phase behavior. Results of calculations of phase equilibria for some nanofluids are described..
