Fig. 2: A temperature drop of an expanding fluid by COMSOL Multiphysics simulation compared with the experiments.
From: Quasi-equilibrium phase coexistence in single component supercritical fluids
a The buffer chamber with 300 bar suddenly expands to an open space having 1 bar. b The experimental measurement is compared with the time- and space-averaged temperature in the simulation results (0–200 ms, red dashed area). c A set of simulations shows the fluid expansion through the check valve of the compressor outlet to the pipe connecting to the main chamber as a function of the initial pipe pressure. d Minimum temperatures for different pipe pressures. The error bands are the standard deviations of each point.
