Design of the Submerged Outlet Structure for Reducing Foam at a Power Plant using a Numerical Model Simulating Air Entrainment

摘要: Anti-foaming agents and foam fences have been used to remove the at outfall of power plants, but there are some problems as consumption maintenance costs insufficiency effect. Therefore, development methods how by stable coastal structure has required. In this study, numerical simulation air entrainment was carried out design submerged outlet for reducing using curtain walls. The rate discharge entrained change according shape weir wall. Hence, it is necessary optimum section through comparison each case. which maximum reduction determined results. addition, found that flow velocity be smaller than 1 m/s depth wall taller height section.
