A spatially-random network model by using measured pore morphology was then set up to simulate the pore scaleflow processes, and to predict the soil water retention curve near saturation.
The modelscale and the ratio of prototype to model for various hydraulic elements are selected in the light of theory of unsteady flow similarity for hydraulic models.
模型比尺和模型中各项水力要素的比例是根据不稳定流模型相似条件选定的。

Finally, separation flow, secondary flow and multi-scale eddy structure are simulated, it indicates that SST model can give a good prediction of turbulence in the draft tube.
