Widom line and noise-power spectral analysis of a supercritical fluid
Widom line and noise-power spectral analysis of a supercritical fluid
We have performed extensive molecular dynamics simulations to study noise-power spectra of density and potential energy fluctuations of a Lennard-Jones model of a fluid in the supercritical region. Emanating from the liquid-vapor critical point, there is a locus of isobaric specific heat maxima, called the Widom line, which is often …
