| 摘 要： | 在水利水电工程中, 泥沙经常会带来负面影响, 需采用合适的研究方法来分析泥沙运动规律. 针对高浓度水沙流动的特殊性, 选择双流体模型统一描述悬移质和推移质泥沙的运动. 该模型不仅考虑了水沙两相之间的相互作用, 同时考虑了颗粒之间的相互作用及两相体积分数的脉动效应. 以Coleman 实验结果为参考, 验证了模型的可靠性. 最后使用模型预测了某引水式电站沉沙池泥沙的沉降情况.

| Abstract: | Since sediment usually has a negative effect on hydropower project, it is necessary to develop appropriate methods to analyze sediment transport. Due to complexity of high concentration granular flow, a three dimensional two-fluid model was proposed to study slurry flows of both suspended load and traction load. The model took into account interaction between particles and water, as well as inter-particle collision and fluctuation of the two phase volume fraction. Numerical simulation of an open-channel sediment experiment of Coleman was used to validate the two-fluid model. Based on the model validation, the deposition effect of a specific desander was analyzed. |
