Deterministic Phase Retrieval Using the LCTperiment. The numerical method is based on a viscous vortex (particle) method. The experimental investigation involves the towing of a cylinder through waves in a laboratory flume, and comparison of the transverse force with a quasi-steady model.

University Series in Mathematics until the steady state wake oscillation was established. The velocity time traces in the wake taken with a LDV were analyzed using a wavelet analysis technique, and time scales of vortical structures were identified and correlated with the flow visualizations.

The pressure behind the cylinder decreases greatly towards the upstream endplate of the cylinder, although there is a strong wedge-shaped recovery of pressure in the region near the rear stagnation. The strong secondary flow behind the yawed circular cylinder is responsible for the recovery region.
