摘要
针对典型一体化自然循环压水堆,基于微液层理论,研究了摇摆条件下微液层厚度和堆芯通道质量流量关系。研究结果表明,摇摆条件下,由微液层理论模型计算得到的微液层厚度随着堆芯热通道内质量流量的增加而增大,能够直接导致边界层厚度的变薄或消失,最终发生传热危机。
Based on the theory of micro fluid layer,the relationship between mass flow micro fluid layer thickness under rolling condition for typical integration natural circulation PWR has been studied.The result indicates that the micro fluid layer(MFL)thickness increases with the increase of mass flow rate of the core thermal channel,which may be lead directly to the boundary layer thickness thinning or disappearing,inducing heat transfer crisis.
