Abstract
The present study validates a large-eddy simulation from the viewpoint of the intermittency of a turbulence field for low-Reynolds-number anisotropic steady turbulence. Analyses based on implicit large-eddy simulation and the Vreman-model are validated. The results of the two analyses are compared with results obtained through direct numerical simulation. The mean value of the global turbulent kinetic energy obtained through the analysis based on the large-eddy simulation is consistent with that obtained through the present direct simulation. The frequency of large-scale vortex structures found in instantaneous fields and higher-order turbulence statistics are examined. The intermittency of the turbulent fields obtained through the implicit large-eddy simulation is higher than that obtained through the other analysis.
