An experimental flow visualization study was done on an oscillating generic ship
model in the Low Speed Wind Tunnel Facility at the Naval Postgraduate School in
Monterey, California. The purpose was to visually analyze the flowlield around the
model while simulating ship motion in rough seas, with a correspondingly modelled
open-ocean atmospheric boundary layer.
The two flow visualization techniques utilized were neutral density helium
bubbles and a liquid aerosol, each technique providing varying degrees of on-body and
off-body analysis. Limited success was achieved with the aerosol, but the helium
bubbles produced excellent photographic results and an accurate visualization oi~ the
oscillating model's flow field was achieved.
