在水平的均匀的紊流液体中,自由运动着的重颗粒速度,加速度轨迹的计算;对于各种不同的技术范围内都是必须的,例如在矿业中的选矿问题,在农业中的风力选种问题,在水利工程中沉砂池的计算,在水文学中悬浮泥砂运动的计算,以及其他问题。在实际工程中已运用了极复杂的设备,但是改造它们的结构几乎还完全是使用实验的方法,因为到现在为止还没有一个在工程应用上很方便的计算方法,因此在这方面所进行的任何工作对于解决这个很少研究但很重要且广泛的问题都是很有益的贡献。在这篇文章里对这个问题一部分基本因素加以阐述,并制定计算水平的水流液体中混合物粒径分配的近似方法。
The calculation of free-moving heavy particle velocity and acceleration trajectories in horizontal uniform turbulent fluids is necessary for a variety of different technical fields, such as mineral processing in mining, wind power in agriculture Species, calculation of grit chamber in hydraulic engineering, calculation of suspended sediment movement in hydrology, and other issues. Extremely complex equipment has been used in practical engineering, but the structure of retrofitting them is almost entirely experimental. As there has not been a computationally convenient method for engineering applications so far, Any job is a useful contribution to solving this seldom-studied but important and broad-based issue. In this article, we illustrate some of the basic elements of this problem and develop an approximate method for calculating the particle size distribution of a mixture in a flowing liquid.
