Research Interests

Dr. Arndt is a Professor Emeritus, University of Minnesota. His major research interests are in the area of fluid mechanics with emphasis on turbulent shear flows and vortex flows; cavitation; aeroacoustics including jet noise and turbomachinery noise; alternate energy with an emphasis on hydropower and wind turbine technology; and aeration technology with a view towards developing cost effective environmental remediation techniques. His research experience includes cavitation in pumps, turbines and marine propellers; supercavitation, investigation of noise radiation mechanisms in turbulent shear flows, bubbly flows and helicopter and jet noise. The principles of bubble formation in turbulent shear flows are being applied to the design of more efficient aeration equipment and ventilation of supercavitating vehicles. His experience in the design of research facilities for cavitation and hydroacoustics has lead to the design responsibility for three major hydroacoustic research facilities in the US, Germany and Korea, one of which is the World’s largest water tunnel. His industrial experience includes underwater rocket propulsion, high-speed marine vehicles and waterjet propulsion. He served as Director of the St. Anthony Falls Hydraulic Laboratory for 16 years and as program Manager of the Fluid Mechanics and Hydraulics Program at the National Science Foundation for 3 years. Dr. Arndt continues his research at the St. Anthony Falls Laboratory of the University of Minnesota where he is working on wind turbine aerodynamics and supercavitation. He is a Life Fellow of ASME, Fellow of the American Physical Society, and Associate Fellow of AIAA.
