Abstract: For the fact that the growing number of high concrete dams built in valley, the problems existing in the dissipation of flow energy become more and more significant. Mechanism of energy dissipation of diffusion by sky-jump is discussed in this paper by means of turbulence theory and test. From the discussion such a conclusion can be arrived at that the essential of energy dissipation of diffusion are actions due to turbulence and due to entrained air. In addition, ways in which the effect of energy dissipation of diffusion can be improved are proposed.
摘要: 本文结合实验结果,应用紊流理论对挑流扩散消能机理进行了讨论。认为扩散消能的本质,是由紊动粘性耗散,以及掺气气泡滞后所引起的附加能耗所构成。此外,文中还指出了增强扩散消能效果的途径。
