基于CFD模型的内陆核电厂厂区流场模拟
Wind field simulation in an inland nuclear power plant based on a CFD model
摘要
Abstract
The basic principle simulating wind field and plume drift of large scale natural draft cooling tower with a CFD software STAR-CCM + was introduced by using an inland nuclear power plant as a case study. How to import the nuclear power plant model established by CAD software SolidWorks2010 into STAR-CCM + was intro- duced, and a whole process of grid-creating and boundary setting was illustrated. The simulation value of STAR- CCM + and the observational value of wind tunnel experiment were compared, and both were consistent. The re- sults indicate that there is a large cavity area behind the cooling tower at the height of 5 m above the ground. The wind speed of cavity area is only 1.0 - 1.5 m/s, and the wind is calm in part area. Side wind speed of cooling tower is 1.66 times of inlet wind speed. At the height of 100 m above the ground,the cavity area is still obvious, while the side wind speed of cooling tower becomes steady compared with inlet wind speed. The wind disturbance phenomenon in cooling tower sides strengthens along the dominant wind direction. The maximum plume rising height of a single cooling tower reaches 690 m at the distance of 3300 m downwind, while that of four cooling towers is 850 m and it is about 1.23 times of a single cooling tower.关键词
