University of Iowa – Hydraulics Towing Tank

Capabilities include:

  • WEC and TEC hydrodynamics
  • CFD model validation


Located in the lower level of C. Maxwell Stanley Hydraulics Lab, the IIHR towing tank has provided researchers with more than 50 years of experimental data. When noted researcher Lou Landweber left the David Taylor Model Basin (DTMB) and joined IIHR in the mid-1950s, he helped build IIHR into one of the nation’s leading ship hydrodynamics research programs. Researchers here have focused mainly on ship hydrodynamics, with an emphasis on free-surface flows as they relate to resistance and propulsion. However, present towing tank work focuses on seakeeping and maneuvering problems, as the traditionally separate areas of resistance and propulsion, seakeeping, and maneuvering begin to merge and CFD methods improve and are able to handle increasingly complex ship hydrodynamics problems.
