我们从实验和理论上研究了圆形水跃的经典问题。通过基本流体动力学，我们研究了控制水跃位置的比例定律，并将我们的预测与实验数据进行比较。我们简单模型的结果与实验和更复杂的方法非常一致。该问题可以有效地用于教育目的，适用于实验研究和许多流体力学概念的理论应用。
We study both experimentally and theoretically the classical problem of the circular hydraulic jump. By means of elementary hydrodynamics we investigate the scaling laws governing the position of the hydraulic jump and compare our predictions with experimental data. The results of our simple model are in good agreement with the experiments and with more elaborate approaches. The problem can be effectively used for educational purposes, being appropriate both for experimental investigations and for theoretical application of many fluid mechanics concepts.
