| 摘 要： | 本文采用了五孔毕托球结合压力传感器，通过微机自动的采样和处理，设计了一套可施测三元流场的测试系统，并测试了一大比尺模型的多股水舌入射水垫塘塘内的三元流态，首次得到水垫塘水流流态的概化图，揭示了多股水看入射水垫塘形成的塘内复杂的流态特征，并将其流态特征归类为三个区：水舌入射区，螺旋流区和扩散区，并对每个流区作了分析。

| Abstract: | In this paper, using the five-holes Pito sphere combined with the pressure transducer and computer for automatic sampling and proceesing, a 3-D velocity measurement system has been designed and the3-D flow regime of a large model scale plunge pool impinging by multiple jets was investigated experimentally. The outline picture of the flow regime of the plunge pool has been obtained initially. The experimental results releaved the complicated flow regime features formed by the multiple jets impinging into the plunge pool. The flow regimes features can be divided into three regions: jet impinging region, spiral current region and divergent region. These three regions of flow regime in plunge pool have been analyzed separatedlly in this paper. |
