Numerical simulation of Dense Gas Compressible Homogeneous Isotropic Turbulence

The decay of compressible homogeneous isotropic turbulence for dense gases is studied by means of Direct Numerical Simulations and Implicit Large Eddy Simulations. A family of heavy fluorocarbons, which exhibit non-classical phenomena, is considered. The thermodynamic behavior of the fluids is modeled by the politropic Van der Waals or the five-term Virial Martin-Hou equations of state, and the results are compared to those obtained for a thermally and calorically perfect gas
