垂荡板水动力的数值模拟

将计算垂荡板的水动力问题简化为二维竖直平板的绕流问题，计算了在各种来流情况下垂荡板的受力，给出了在计算模型下流场后尾涡片的发展图景。与试验结果对比后发现，尽管计算模型和试验时的三维模型差距很大，但只需要调整计算条件，计算结果与试验结果即可较好地吻合。这表明，在类似的情况下对于不同形状的平板，存在可以简化到二维的可能。

Numerical Simulation of Hydrodynamic Forces of Heave Plate

The hydrodynamic force acting on a heave plate can be computed by simplifying it to a two-dimensional problem. In this situation, the flow around the heave plate can be regarded as a flow past a plate normal to the free stream. The generated hydrodynamic force was computed in various incident flows. Compared with the experimental data, it is found that although the computation model is much different from the real model in the test, their results are similar. Such numerical results can be obtained by adjusting height of the plate and oscillating velocity in computation. This comparison result indicates the plates of different shape may be simplified to two-dimensional bodies because of their special plate structure forms.
