Velocity Measurement of Air-Water Mixtures
Publication: Transactions of the American Society of Civil Engineers
Volume 119, Issue 1
Abstract
The search for an adequate explanation of the physical phenomena of natural occurrences is invariably held in abeyance by the lack of suitable measuring instruments and standards of measurement. Once accurate and detailed measurements can ‘be made, the analytical treatment· of a wide range of conditions is usually possible on the completion of basic experimentation. The insufflation of air into high-velocity streams of water in open channels is one of the many fluid mechanics phenomena still retarded in its complete analytical explanation by the inadequacy of instrumentation required for experimental observations. This paper traces the development and use of a velocity-measuring instrument at the St. Anthony Falls Hydraulic Laboratory, University of Minnesota, at Minneapolis. This instrument, referred to as the St. Anthony Falls (SAF) velocity meter, is particularly useful in the undertaking of velocity traverses in air-water mixtures.
