摘要
本文提出了悬移质颗粒运动方程的新解,相对于早期将由流体加速度引起的颗料运动速度Up划分为──水体速度u、通过静止水体的沉降速度ω、和偏移速度V三个部分的研究成果更为准确。由于施滞力可以用重力和比值|Up-u|/ω来表示,而使问题进一步简化,尽管E.G.Ho(1964)和Svendsenetal(1997)已经提出了层流条件下,颗粒运动的线性解,但本文提出了更进一步的定量分析解。
A new solving to the equation of motion of the suspended load particle is given in this paper. The result ismore accurate comparing with the early achievements that the moving velocity of the suspended load particle UPcaused by fluid acceleration is divided into three parts of the water body velocity (u ), the settlement velocitythrough still waters (co) and deviation velocity (v ).Because towing tension can be represented as gravity and ratio | Up-u | /to, the matter is further simplified,although E. G. Ho (1964) and Svendsen et al (1977) had suggested a linear solution of particle movement underthe laminar condition, the further quantitative ana1ysis solution is advanced in this paper.
