Uncontrolled air entrainment in pressurized adduction systems can cause serious operational problems and costly downtime. This paper describes the use of a combination of two- and three-dimensional CFD analysis to study a broad range of aspects for the design of a de-aeration structure, to enhance safety and reduce operational issues. The results of the research were applied at a hydro plant in Lao PDR, where a fully pressurized flow system can operate safely with two independent waterway branches.
