本文应用量纲分析和相似类比方法,论证紊流力学中的混合长度和涡旋微尺度的物理意义在紊流微结构中都具有波长性质。还论述了紊动波长与涡体运动的关系,并提出在混凝动力学中紊流能耗越大,涡旋微尺度越小,涡体半径越小,而涡体运动(旋转)速度越大的相互关系。为合理控制紊流能耗以提高水力混合絮凝设备效能,提供了理论解释。
In this paper, dimensional analysis and similar analogy methods are used to demonstrate that the mixed length of turbulence mechanics and the physical significance of vortex microscale have wavelength properties in turbulent microstructures. The relationship between turbulent wavelength and turbulent motion is also discussed, and it is proposed that the larger the turbulent energy in the kinetics of coagulation, the smaller the vortex microscale, the smaller the vortex radius, and the faster the vortex motion (rotation) speed. Great relationship. In order to reasonably control the turbulent energy consumption and improve the performance of the hydraulic mixed flocculation equipment, a theoretical explanation is provided.
