IIHR Engineers Win $411,550 Federal Grant

Frederick Stern, professor of mechanical engineering in the University of Iowa College of Engineering and research engineer at IIHR - Hydroscience & Engineering, and Joseph Longo, IIHR assistant research engineer, have received a one-year, $411,550 grant from the U.S. Office of Naval Research to secure advanced equipment for IIHR under the Defense University Research Instrumentation Program (DURIP). The grant also calls for the UI and IIHR each to provide additional amounts of $205,775, bringing the total value of the grant to $823,100.

The IIHR project, formally known as the "Towing Tank Maneuvering Test Flow-Map Measurement System," will provide equipment useful for maneuvering tests with ship models and simultaneous 3-D ship model flow-field measurements with a towed, 3-D particle image velocimetry measurement system. IIHR Director V.C. Patel says that the award is evidence of the excellence of the ship hydrodynamics program at IIHR. A unit of the UI College of Engineering, IIHR is one of the world's premier and oldest fluids research and engineering laboratories where students and researchers from around the world study and research such phenomena as water flow along rivers, flash flood forecasting, and ship design.

Stern, project director, says: "The grant will further advance research capabilities for future focus on large amplitude motions and maneuvering, which are required to meet the goal of realizing simulation-based design (SBD) for naval hydrodynamics. SBD merges the traditional fields of resistance and propulsion with sea-keeping and maneuvering and, with the inclusion of power systems and open-ocean and littoral environmental effects, offers the possibility of completely out-of-the-box concepts for future naval ships to meet the challenges of the 21st century Navy."

Stern, who joined the UI faculty in 1983, is an international leader in developing computational ship hydrodynamics, advanced towing-tank measurement systems for modeling and validation, and computational and experimental uncertainty analysis. A Fellow of the American Society of Mechanical Engineers (ASME), he has published numerous articles in peer-reviewed journals and has developed revolutionary multimedia methods for integrating classroom lectures, laboratory experiments, and computer simulations, and uncertainty analysis.

The Department of Defense 2003 fiscal DURIP program involves some $27 million awarded to 75 academic institutions to support the purchase of research instrumentation. The 125 winning projects were selected from among 949 proposals submitted in a merit-based competition.
