| 摘 要： | 提出了一个预报圆形气泡羽流特性的k－ε－E湍流模型。对静止环境中的圆形气泡羽流流场进行数值模拟，得出了气泡羽流的流速场和浓度场。预报结果表明，气泡羽流的流速及气泡浓度在横断面上的分布为高斯型曲线分布，模拟结果与实测资料对比两者吻合较好。

| Abstract: | A κ-ε-E turbulence model is established to predict the property of round bubble plumes. Numerical simulation of round bubble plumes in still environment is performed to obtain the distribution of velocity and gas holdup. The results of bubble plume prediction indicate that the distribution of flow velocity and gas holdup over the cross section appears to be type curve distribution, the simulation results are found to be in good agreement with real measured data. |
