| 摘 要： | 水利水电工程中，高速挑流水舌在空气中的掺气及空气对其水流结构有很大影响，随着对消能与雾化问题认识的深入，这种影响愈来愈有必要加以深入研究并在工程中加以考虑。本文对平面充分掺气散裂射流的挑距进行了分析，并对其空中消能率随初始挑角，初始佛汝得数及初始含水浓度的变化进行了探讨。

| Abstract: | Aerated jets, such as the jet flow behind the flip bucket of the overflow dam frequently occurs in hydraulic engineering. The characteristics of the aerated jet largely depend on air concentration and air resistance. In this paper the trajectory as well as the energy dissipation rate of the aerated jet were investigated to examine the effects of air concentration and air resistance. The analytical results are in accordance with the experimental ones. |
