| 摘 要： | The radial and axial distribution of mean 1iquid velocity were measured by a.hot-filmanemometer at the impeller region in an aerated and stirred tank 0.287m in diameter.The tangentialjet model for impeller discharge flow used for single phase flow was modified to conform with thecharacteristics of gas-liquid flow.The radial and axial velocity profiles at the impeller region in thegas-liquid stirred tank were calculated by the model The results predicted by the model were in goodagreement with those obtained in experiment.

| Abstract: | The radial and axial distribution of mean liquid velocity were measured by a, hot-film anemometer at the impeller region in an aerated and stirred tank 0.287m in diameter. The tangential jet model for impeller discharge flow used for single phase flow was modified to conform with the characteristics of gas-liquid flow. The radial and axial velocity profiles at the impeller region in the gas-liquid stirred tank were calculated by the model The results predicted by the model were in good agreement with those obtained in experiment. |
