Princeton/ONR HRTF
ONR/DURIP grant to construct wind tunnel based on same principle as Princeton/DARPA-ONR Superpipe (ReD 31 x 10 3 - 35 x 10 6)
- a feasible, cost-effective means of achieving high Re
-
studies of hydrodynamic forces, moments and flow-fields produced by submarine-type shapes
- working fluid is air, p up to 200 atmospheres (r/m x 160)
- Re variation through p, v, x changes
- maximum Re 175 x 10 6 / m
- 1/5 full-scale submarine models
evaluation of current scaling laws in light of new high Re data
development of new scaling for turbulent flows at industrial/military Re
