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。
Based on the experimental results, this dissertation discusses the mechanism of diffusive energy dissipation by using turbulent flow theory. It is considered that the essence of diffusion dissipation consists of turbulent viscosity dissipation and additional energy consumption caused by the lag of aeration bubbles. In addition, the article also pointed out ways to enhance the effect of diffusion and energy dissipation.
