摘要
总结泄洪雾化对工程的影响,分析泄洪雾化的来源和雾化区的划分,指出雾化源主要来自水舌落水附近的喷溅;探讨入水喷溅的机理,给出重力、空气阻力和水舌风作用下喷溅的纵向距离和横向喷溅宽度数学表达式,确定喷溅范围和强度;分析提出雾化范围的预报估算式,最后对雾化危害的防护提出具体意见。
This paper presents the influence of atomization by discharge flow on engineering projects, the atomization sources and the delimitation of various zones. The main source of atomization is found to be the impinging sprays near the nappe impingement region. The mechanism of nappe impinging sprays is also investigated. The authors developed analytical formulas to estimate the sphere of influence, both streamwise and spanwise, impinging sprays under the action of gravity, air drag and nappe wind. In addition, the intensity of the spray can also be determined. Based on the analysis of data a formula predicting the scope and range of atomization is presented. Finally, some practical suggestions to protect from harmfuleness of atomization are brought up.
