Udaykumar Receives $750,000 Grant To Develop Computer Simulation Programs

H. S. Udaykumar, associate professor of mechanical and industrial engineering in the University of Iowa College of Engineering and associate faculty research engineer at IIHR-Hydroscience & Engineering, has received a five-year, $750,000 grant from the U.S. Department of Defense Air Force Research Laboratory to develop computer simulation techniques useful in studying phenomena ranging from high-speed impacts to the operation of heart valves.

Titled "High-Accuracy, Efficient Eulerian Methodology for 3-Dimensional High-Speed Material Response," the project is aimed at developing an advanced computer program that can run on massive parallel computer architectures. While the Air Force may find the program useful for studying how blast waves generated by high-speed impacts or explosions interact with various materials, Udaykumar and his students plan to use it to study fluid-structure interaction problems, including the functioning of heart valves, the mechanics of intestines and the manufacture of high-strength composite materials.

Udaykumar's special fields of knowledge include computational fluid dynamics, moving boundary problems in fluid mechanics, biofluid mechanics and materials processing. His numerical simulation research interests have application to such problems as the dynamics of white blood cells in human circulation, the fluid mechanics of the human intestine and plaque growth in arteries.
