Taylor-Couette flow

Researchers at Norwestern University used a TSI PIV system to investigate wavy Taylor vortex flows between two concentric rotating cylinders. In addition to obtaining full field, time-resolved, two-dimensional vector maps, special software was developed to capture a time sequence of over 16,000 smaller image pairs. These were processed using TSI’s Insight PIV software and the resulting time-resolved velocity data used to calculate the power spectral density of velocity the flucutations.
