AP1000中 ADS-4液体夹带实验研究
Experimental Research of Liquid Entrainment through ADS-4 in AP1000
摘要
Abstract
With the T‐junction formed by the fourth stage automatic depressurization system (ADS‐4) and hot leg in AP1000 nuclear power plant as object of study ,a small‐scale experiment research on entrainment at T‐junction was performed .The visualiza‐tion research indicates that the entrainment phenomena through a large size branch are apparently different from those through a small branch .Two entrainment mechanisms could be found in the stratified flow entrainment area .Intermittent flow entrainment tends to occur at a lower Froude number and a lower gas chamber height .Annular flow entrainment always arises at a higher Froude number .Also ,the experimental research shows that the reverse flow is observable in a large size branch inlet .The geometry of the branch has an important effect on the onset entrainment .In addition ,liquid cross‐flow does not seem to affect the onset entrainment .关键词
