Abstract

The flow around a 3-1 prolate spheroid near the critical
Reynolds number is investigated experimentally and numerically.
This work was conducted as part of a larger project to
examine the flow around Unmanned Underwater Vehicles. The
experimental investigation has been performed in a water tunnel
at the Australian Maritime College. Fast response pressure
probes and a 3-D automated traverse have been developed to
investigate the state of the boundary layer. A commercial CFD
code has been modified to allow the experimentally determined
boundary layer state to be included in the computation. Qualitative
and quantitative comparisons between the measured and
calculated results are discussed. The tests on the spheroid were
conducted within a Reynolds numbers range of 0 .6 ×106 to
4×106. The results presented here are for an incidence of 10 .
