Laboratory Studies of Cavitation in Corps of Engineers Hydraulic Structures

by John L. Grace, US Army Engineer Waterways, Experiment Station, Hydraulic, Structures Div, Vicksburg, MS, USA,



Document Type: Proceeding Paper

Part of: Water for Resource Development

Abstract:

A selected bibliography of significant hydraulic laboratory research efforts by the U. S. Army Engineer Waterways Experiment Station to identify the likelihood of and means of preventing cavitation and severe damage in various types of hydraulic structures and appurtenances is presented. Generalized experiments and specific project model studies are reviewed. Data and experiences obtained with certain prototypes that were modeled are discussed. Successful solutions and practices involving control of geometry, flow characteristics, and aeration of flow are described. Recent developments that permit prediction and control of reaeration and gas transfer in certain hydraulic structures are identified. The author's philosophy and approach recommended for modeling cavitation phenomenon and interpreting model results to aid design of various hydraulic structures and appurtenances are presented.
