NUMERICAL SIMULATION OF WATER HAMMER IN PSEUDO-HOMOGENEOUS SOLID-LIQUID TWO-PHASE FLOWS Ⅱ. VALIDATION

本文是《伪均质固液两相流水击的数值模拟》的第二篇。在本文中，根据固液两相流水击实验，对前一篇论文中建立的伪均质固液两相流水击数学模型进行了验证，并对目前工程计算中采用的单相流修正模型进行了验证。计算结果与实验结果的对比表明，两相流模型的计算值与实测值符合较好，而单相流修正模型的计算结果误差较大。因此新建的伪均质固液两相流水击模型可以用于工程计算。

This is the second of two papers that discuss the simulation of water hammer in pseudo-homogeneous solid-liquid two-phase flows. In the first paper, a new mathematical model has been developed. In this paper, the new model and other water hammer computing models for sin gle-phase flows that are usually employed to compute the water hammer of solid-liquid flow in particles' transport engineering, are validated by comparing the model predictions to available experimental data. These comparisons show that the computational results of the new model are much closer to the measured data than the models for single-phase flows and the new model can be used in engineering computation of water hammer in pseudo-homogeneous solid-liquid two-phase flows.
