摘要
本文在均质高浓度紊流试验研究成果的基础上,应用宾汉定律和紊流随机理论,研究了均质高浓度非牛顿宾汉紊流的紊流结构。导出了时均流速和阻力系数在光滑区、粗糙区和过渡区的统一公式,并得到了现有实测资料的初步验证。
The turbulent structure of motion of homogeneous hyperconcentrated fluid which is known as Non-Newtonian Bingham fluid is studied in this paper. On the basis of Bingham's relationship of shear stress and the stochastic theory ef turbulent flow developed by Dou Guoren, the mean velocity distribution and drag coefficient laws for such flows in all smooth, transition and rough regions are deduced. These theoretical results. are preliminarily compared with experimental data, and satisfactory agreements between them are obtained.
