【 摘 要 】

References(16)Low-frequency fluctuations in agitated vessels are found to be unstable phenomena of flows. The fluctuations can be generated when flows are ejected from an impeller into rotating flows formed by the rotating impeller in which centrifugal force instabilities occur. It is also shown that low-frequency fluctuations can be represented by carrying out a direct numerical simulation and promote the mixing of fluids in agitated vessels.
