Thermodynamics of Bidisperse Ferrofluids in Zero External Magnetic Field: Theory and Simulations

Article Preview

Abstract:

The thermodynamic properties of a ferrofluid modeled by a bidisperse system of dipolar hard spheres in the absence of external magnetic field are investigated using theory and simulations. The theory is based on the virial expansion of the Helmholtz free energy in terms of particle volume concentration. Comparison between the theoretical predictions and simulation data shows a great agreement of the results.
