Air detrainment in high-speed chute flows
(2002)Hydraulic Measurements and Experimental Methods 2002Air added to high-speed chute flows is known to reduce the potential of cavitation damage at the chute floor. Therefore hydraulic model experiments using advanced fiber optical instrumentation were conducted to investigate two-phase flows with regard to air detrainment. Two different set-ups for air addition to water flow were studied, namely: (1) Pre-aerated discharge supply, and (2) Chute aerator. Differences between the two set-ups are ...Conference Paper -

Pier and abutment scour - New laboratory data
(2002)Proceedings of First International Conference on Scour of FoundationsThe purpose of this paper is threefold: (1) Presentation of a scour installation used over the past 6 years; (2) Summary of results pertaining to the Shields entrainment criterion that was expanded for bridge pier and bridge abutment; and (3) Discussion of new results. Based on a long term investigation of scour, the experimental method was improved to result presently in an installation that might be of general interest. Accordingly, ...Conference Paper -
