Measurement of the flow structures in the wakes of different types of parachute canopies
We measured flow structures with stereoscopic particle image velocimetry (stereo-PIV) in the turbulent wakes of three parachute canopies, which had the same surface area, but different geometries. The tested parachute canopies included ribbon canopy, 8-branches canopy, and cross canopy. The obtained...

| description | We measured flow structures with stereoscopic particle image velocimetry (stereo-PIV) in the turbulent wakes of three parachute canopies, which had the same surface area, but different geometries. The tested parachute canopies included ribbon canopy, 8-branches canopy, and cross canopy. The obtained results showed that the geometry of the parachute canopies had significant influences on the flow structures in the wakes of these three canopies. In addition, the variation of Reynolds number did not lead to a dramatic change in the distributions of velocity, vorticity, Reynolds stress, and turbulent kinetic energy. |
