The St. Anthony Falls Laboratory (SAFL) was designed and built in the 1930s under the direction of Lorenz G. Straub with funds from the Works Progress Administration and the University of Minnesota. The building was dedicated on November 17, 1938 and the Laboratory began its work in hydraulic and river engineering research as part of the Department of Civil Engineering.

Today SAFL is an interdisciplinary fluid mechanics research and research training facility of the College of Science and Engineering. Research focuses on environmental, energy, and health challenges.

Current information about SAFL and its programs is at http://www.safl.umn.edu.

    An Experimental Study of The Hydroelastic Instability of Supercavitating Hydrofoils
    (St. Anthony Falls Hydraulic Laboratory, 1967-02) Song, Charles C. S.; Almo, John
    Some experimental findings concerning the flutter characteristics of two-dimensional supercavitating flat plate hydrofoils are reported herein. The experiment was carried out in a freejet water tunnel using wedge-shaped hydrofoils (practically rigid) elastically supported to permit two-degree of freedom motions in translational and rotational modes. Critical flutter speed, flutter frequency, flutter amplitude ratio, and damping factor were measured for various elastic and flow conditions. The measured stability boundary curves agree, qualitatively,with an existing linear theory.

    The Influence of Drag Reducing Polymer Additives on Surface Pressure Fluctuations on Rough Surfaces
    (St. Anthony Falls Hydraulic Laboratory, 1971-09) Killen, John; Almo, John
    Experimental measurements were made to determine the effect of drag reducing polymer additives on the surface pressure fluctuations on smooth and rough surfaces in relative motion with water. Changes in surface pressure fluctuation intensity were found to be closely related to changes in surface shear when shear change was caused by the addition of drag reducing polymer, by a change in surface roughness, or by both of these.
