Figuring out flow dynamics

Researchers at Caltech have developed a new way to analyze turbulent flow near walls, which can help reduce drag and fuel consumption in aircraft and ships. By breaking down complex equations into smaller blocks, they found that commonly observed features of wall turbulence can be explained by superposing just three response modes.
