摘要
Abstract
Theoretical and practice experiences show that it is favorable to speed up mixing and dilution of the liquid effluent within the area near its discharging outlet by adopting porous diffuser for the inland nuclear power plant.Based on the near area simulation tools——Cornell Mixing Zone Expert System,CORMIX recommended by the U.S.EPA,the porous diffuser for the inland nuclear power plant under the hydrological condition of low flow rate is studied herein.The analysis shows that when the arrangement of the porous diffuser is nearshore under the condition of low environmental flow rate,relative stronger jet flow and deeper water depth,(1)the length of the main tube of diffuser Lnis positively correlated with H (the minimum relative dilution ratio at the downstream cross-section of the discharging outlet),the spout diameter D is negatively correlated with H and the water depth of the spout HD is positively correlated with H,while the effluent flow rate Q is positively correlated with H as well under the condition of the same heat exhaust;(2) for H1 000 m,the order of the sensitivities of all the geometric parameters from high to low is to be:the spout diameter D,the spout number n and the main tube length Ln.The study conclusion can provide a reference for both the design and optimization of the liquid effluent discharge project for inland nuclear power station.关键词
