非均质流高浓度管流阻力特性研究

On the Mechanism of Drag Reduction in High Concentration Non-Homogeneous Pipe Flow

本文针对火电厂粉煤灰高浓度管道水力输送非均质流管流中切应力及流速分布的基础上,提出了非均质流高浓度管流中层流、紊流阻力公式,通过实测资料验证,理论计算与实测资料之间关系比较一致,说明模型设想及理论公式是合理的。

In this paper a method for calculating the resistance force in high concentration non-homogeneous pipe flow is suggested. Comparing with experiment, it is shown that the theoretical results are in good agreement with the experimental ones.
