The onset of liquid entrainment during discharge from two branches on an inclined wall

Abstract

AbstractA theoretical investigation has been conducted for predicting the critical liquid height at the onset of liquid entrainment during dual discharge from a stratified two‐phase region through branches mounted on an inclined flat wall. The centerlines of the two branches are parallel and they fall in a common vertical plane. Two models have been developed; a simplified point‐sink model and a more‐accurate finite‐branch model. Predictions from the two models are shown to be in good agreement for the condition of high flow rates from the branches, while the finite‐branch model is necessary for accurate predictions at low branch flow rates. This behaviour has been confirmed experimentally for the vertical‐wall configuration.
