摘要
以实验为依据，对影响旋流长度的因素进行了详细的分析，得到了环空排量、流体性能、旋流器结构参数诸因素对旋流长度的影响规律。建立了旋流长度公式。
The paper detailedly analyses the factors affecting whirlflow length and finds out the rules of effectof factors such as annular flow velocity,fluid properties and whirl flow centralizer structure parameters onwhirlflow length,and establishes a calculation formula of whirlflow length.
