As rain pours down onto a London street, umbrellas pop open and pedestrians scatter. Small fast-moving rivers race down the street, eventually flowing into sewers beneath the city. The storm runoff quickly overtaxes the Victorian-era combined sewer system, parts of which are the “lost rivers of London” that were covered over as the city grew. […]

Sanada Improves Visualization for Ship Hydro
IIHR’s Yugo Sanada is using reflected light to help researchers better visualize the water surface for advanced ship hydrodynamics research.
CFD Modeling
IIHR—Hydroscience & Engineering is leading a worldwide revolution in the development and application of computational fluid dynamics (CFD), in support of simulation-based design (SBD). Researchers at IIHR use SBD — a sort of virtual reality, supported by model-scale experiments — to develop efficient new ways to design and test engineering designs and prototypes. Computer simulations […]

Building a Digital Lung
IIHR Research Engineer Ching-Long Lin is a key player in a project to develop a digital model of the lung—a task so complex it was once considered beyond the processing power of the largest supercomputers. Lin, who is also a professor of mechanical and industrial engineering at the University of Iowa, was recently awarded a […]
