Study on Differences in Turbulence Statistics between Compressible and Incompressible Low-Reynolds Number Turbulent Channel Flows Using Semi-Local Scaling

Abstract

The differences in turbulence statistics between compressible and incompressible turbulent channel flows are investigated at low-Reynolds numbers using semi-local scaling. DNS of the compressible turbulent channel flow between isothermal walls at low-Mach numbers and DNS of the incompressible flow are performed. It is revealed that the reduction in the pressure-strain correlation term is due to the reductions in RMS velocity-derivative fluctuations and in the absolute correlations between pressure and velocity-derivative fluctuations in the compressible turbulent channel flow at low-Mach and Reynolds numbers.
