摘要
目前较多的河工模型试验都面临模型表面糙率较小的问题。本文介绍了在河工模型中提高表面糙率的方法,并对人工加糙糙率的计算方法进行了总结归纳,对满足阻力相似及提高模型的相似度具有重要意义。
More movable-bed model tests suffer from problem of low model surface roughness currently. In the paper, method of improving surface roughness in movable-bed model is introduced. Calculation method of manually increasing roughness is summarized and concluded, It has important significance on meeting resistance similarity and improving similarity of model.
