不同质材料非恒定流整体变态模型律及设计实例

Model law and design case of monolithic distorted model for unsteady flow: a model made of different materials

同一水电站或抽水蓄能电站输水系统水力模型中,可采用不同的材料制作模型,它既可解决电站水头较高时,对模型材料的强度要求,也可解决直接观察流态的要求.所推求的物理量的模型比尺,可适用于一般电站的模型设计,对水电站水力过渡过程的模型试验具有普遍的指导意义.

Different materials can be used to fabricate the hydraulic model for the water conveyance system of a hydropower station or a pumped storage station. In this way,the requirements of both the strength of materials under higher head and the direct observation of flow patterns inside the pipe can be met. The model scales of the physical parameters deduced hereinafter can be applied to the design of hydraulic model for hydropower station and have the practical importance for the model test of hydraulic transients therein.
