Numerical and experimental investigation of a confined plunging liquid jet system [PDF]

open access: yes, 2012
In a confined plunging liquid jet (CPLJ) system, a liquid jet is allowed to fall in a partially submerged narrow downcomer tube. Liquid jet impingement at gas-liquid interface leads to entrainment of gas, which is dispersed down the downcomer tube in to ...
