摘要
建立了计算掺气设施水力特性的数学模型和挑坎掺气槽坎高的优化目标函数 ,对原型掺气槽的体型优化进行了研究。研究表明 ,掺气设施的优化坎高主要与来流 Fr数有关 ,来流 Fr数愈大 ,所需坎高愈小 ;来流 Fr数愈小 ,所需坎高愈大。
In this paper, a mathe matical mode l for calculating the air demand of the aerator is established, and the target m athematical function for optimizing the shape of the aerator is proposed. The ae ration character and the optimum shape of a prototype aerator are investigated. The optimum area of the air slot and the optimum height of the ramp or step are calculated. The results are in good agreement with the measured data. The metho d proposed herein may be used for preliminary design purposes.
