Based on the relationship between energy and flow within the bed - surface layer , a relationship between the bedload sediment transport rate and effective stream power within the bed - surface layer is derived 摘要基于床面层内的水流能量关系,推导了推移质输沙率与床面层内有效水流功率的关系式。
What is new is the application , which by an inversion of the energy flow in its operation , turns the archimedes screw trough pump into a power generator for the extraction of energy 水力螺旋发电机的独到之处在于对水流能量进行逆向利用,把阿基米德螺旋泵转变成一个可以从水流中提取能量的发电机。
Applying the energy equation and boundary layer theory , this article also analyzed the relationship of energy transformation of overflow , and obtained the experience index and formula of instability critical conditions 并应用水流能量方程和边界层理沦,研究了围堰过水时的水流能量转换关系,得到了稳临界条件的指标和经验判别式。
One of the main reasons of the step spillway having greater energy dissipation is that the potential energy of the flow continuously transforms to the kinetic energy along the spillway and the kinetic energy partially transforms to the turbulence kinetic energy , and the flow energy is finally dissipated by means of turbulence dissipation 研究表明,阶梯坝面水流能量耗散较大的重要原因之一是由于势能沿程不断转化为动能,而动能又部分转化为紊动能,进而由紊动耗散的方式而消耗。
