运用一维流体动力学模型对 2 0 0MW核供热堆余热排出系统的余热排出过程进行数值模拟 ,并对该系统的排热能力及其影响因素进行了分析。分析表明 :余热排出系统的空冷器面积和空冷塔高度是影响余热排出能力的主要因素 ,主换热器与空冷器间的高度差的影响次之
The one-dimensional fluid dynamics model was used to numerically simulate the waste heat removal process of the waste heat removal system of a 200MW nuclear reactor. The heat removal capacity of the system and its influencing factors were also analyzed. The analysis shows that the air cooler area and air-cooling tower height of waste heat removal system are the main factors affecting the capacity of waste heat removal. The height difference between main heat exchanger and air cooler is the second
