摘要
指出雾化流溅水区长度的确定依赖于溅抛水滴的初始状态及随后运动的准确把握.建立了水滴与水面碰撞的简化模型以获得溅抛水滴运动的初始状态,并对溅抛水滴在重力、浮力与风阻力作用下的反弹斜抛运动进行了深入分析,在此基础上提出了新的溅水区长度计算公式,并与已有模型试验及原型观测资料进行了比较.
The splash length of the aerated jet strongly depends on the initial state and the corresponding motion of the splash water drop.A simplified model for the impact of the water drop at the outer edge of the aerated jet against the downstream water surface is established to get the initial state of the splash water drop; and the motion of the splash water drop under the effect of gravity, buoyancy and wind resistance is analyzed. A new formula for the calculation of the splash length is suggested based on the above results; it is in good agreement with the data of model test and prototype observation.
