University of Iowa News Release

A University of Iowa researcher recently received a three-year, $333,348 grant from the U.S. Office of Naval Research to enhance ship design by further improving the use of computer code to simulate fluid flow with air bubbles around ships.

Pablo Carrica, associate professor in the University of Iowa College of Engineering Department of Mechanical and Industrial Engineering and research engineer at IIHR-Hydroscience & Engineering, says that the project "Multiphase Flow Tools for Marine Applications" will improve multiphase flow research.

"The presence of bubbles in the wake of a ship is an important part of the signature of the vessel and greatly affects its detectability," Carrica says. "Bubbles also have important effects on the cavitation and efficiency of a propeller. This project aims to improve the simulation tools for bubbly flows around ships, with stress on the simulation of bubbly wakes."

Carrica added that the project continues a long tradition at IIHR-Hydroscience and Engineering of developing numerical tools for the Navy. Carrica's colleague on the project will be graduate student Alejandro Castro, who will work full time on the project.
