摘要
在清水旋转射流研究的基础上，研究了高分子聚合物添加剂对旋转射流结构特性及破岩效率的影响规律。试验结果表明，高分子添加剂对旋转射流的基本结构影响不大，只是加快了射流的衰减速度，增大了射流的截面积；在合适的浓度范围内，高分子添加剂可以提高射流的破岩能力。
Based on water rotary jet study,the influence rules of macromolecule polymer additives on the configuration character and erosion effect of rotary jet are studied.The experimental results show that macromolecule polymer additives only accelerate the attenuation speed and enlarge cross area.However,it has little effect on the basic configuration character of rotary jet.In proper concentration range,macromolecule polymer additives can improve erosion effect.
