概要

• 論文の詳細を見る

• Homogeneous turbulent flow with no mean velocity in a rotating frame is analyzed using a two-scale direct-interaction approximation to investigate the system-rotation effect theoretically. On this basis, the system-rotation effect on the energy spectrum is discussed, and a model equation for the energy dissipation rate subject to the combined effects of unstationarity and system rotation is derived. The latter is tested using experimental and direct-numerical-simulation results and is shown to be in good agreement with them.
