【摘要】 为了提高洞塞内的最小压强,扩大洞塞式消能工的应用范围,提出了一种新型的内流式消能工———组合式洞塞消能工,并用k ε模型计算了组合式洞塞消能工的水力参数.计算结果表明,与洞塞式消能工相比,组合式洞塞消能工能显著提高洞塞内的最小压强和水流空化数,并且不会明显降低消能率.更多还原

【Abstract】 For improvement of the minimum pressure in plugs and extension of the application range of the plug energy dissipator, a new type of energy dissipator-the combined plug energy dissipator was proposed, and the k-ε model was used for calculation of the hydraulic parameters of the energy dissipator. The calculated result shows that the combined energy dissipator can greatly improve the minimum pressure in plugs and cavitation number of water flow as compared with the single plug dissipator, and the efficiency of energy dissipation does not decrease obviously.更多还原
