Abstract
A powerful computational technique, large-eddy simulation, helps researchers study the detailed flow dynamics in the tip-gap region of hydraulic turbomachines. LES also helps researchers investigate ways to mitigate undesirable effects, such as cavitation, which can lead to reduced performance, increased noise, and structural vibration and erosion.
