5.7 Velocity Results
VF-1600 is chosen because it has the largest limiting cage size of the materials
tested. The maximum possible VF-1600 cage diameters for top-flow and side-flow are
averaged and then divided by two to obtain a cage diameter able to withstand higher than
one knot flow velocity. This cage diameter, 19.2 m, is used for a velocity test on the
cage. The cage withstands the same maximum flow speed of 1.6 knots in both top and
side flow cases before wrinkling occurs. In top-flow, cage diameter decreases 10.183%,
while in side-flow, cage x-diameter increases 4.027%, and cage y-diameter decreases
17.792%. These deflections are reasonable for an inflated flexible membrane cage of this
size and correspond to the expected deformation results shown in Section 5.4.
