High Reynolds Number Boundary Layer Scaling on a Large Hydrofoil (HIFOIL)
Abstract
Velocity profiles were measured on a large hydrofoil model to investigate the Reynolds number dependence in a range of 6x1O(exp 6) to 6xlO(exp 7). The friction velocity and skin friction are computed directly from the velocity measurements using the universal velocity-distribution law. The boundary layer profiles are also numerically integrated to yield displacement and momentum thickness, as a function of Reynolds number. Measurements from the foil pressure-side, which is essentially a flat plate, are shown to be in good agreement with skin friction measurements at the same Reynolds numbers. A scaling analysis of the measurements reveals approximately a 1/l0th power-law relationship of the displacement thickness with Reynolds number.
