Experimental investigation of upper plenum entrainment in AP1000

Literature survey of droplet entrainment from water pools

“…Another factor that affects the entrainment is the Bernoulli's effect. This latter was notable in many experiments (Bagul et al, 2019), (Bagul et al, 2018a), (Bagul et al, 2018b) and (Kim and No, 2003), No, 2005a, 2005b), (Sun et al, 2014), (Qiu et al, 2015), (Sun et al, 2015), (Xiang et al, 2016), and simulated numerically (Lu and Xie, 2017a), (Lu and Xie, 2017b), (Bagul et al, 2019), (Bagul et al, 2018b).…”

Measurement Method and Experimental Analysis of Liquid Entrainment for a Flooded Evaporator of a Water-Cooled Centrifugal Chiller Based on Energy Balance

“…According to the different flow structure and liquid carryover mechanism, there are three types of liquid entrainment. The first type is liquid carryover by gas flow in straight tubes [1][2][3][4] and the second type is carryover through T-branches [5][6][7], the third category is the liquid entrainment in a liquid pool [8][9][10]. Liquid entrainment in straight tubes is caused by the shearing effect of the turbulent gas flow on the annular liquid film, while entrainment in the T-branches is caused by the destabilization of the gas-liquid interface under the pressure difference between the main and branch tubes and entrainment in the pool is due to the boiling and bubbling gas flow from the liquid pool.…”

“…Due to the differences in the flow patterns in the pool droplet generation mechanisms, the momentum-controlled region is further divided into three sub-regions based on different levels of gas fluxes, but the exact form of entrainment correlation is not given when the gas flux is high. Sun et al [9] experimentally studied the pool entrainment with side exit in the near-surface region. Zhang et al [10] studied pool entrainment with and without side exit in the momentum-controlled region and proposed a new correlation with side exit in the high gas flux region.…”
