Dynamics and Acoustics of Trailing Edge Flows at High Reynolds Numbers
Abstract
This project involved high Reynolds number testing and measurements of the flow around a two-dimensional hydrofoil having a Navy-relevant cross section. Three multi-week test campaigns in the US Navy's William B Morgan Large Cavitation Channel were completed. These experiments extended the Reynolds number range of prior hydrofoil tests by more than an order of magnitude. The measurements included laser-Doppler velocimetry profiles and spectra, particle-imaging velocimetry flow fields, static surface pressure distributions, dynamic surface pressure fluctuations, and hydrofoil vibration. This experimental effort emphasized the flow physics leading to trailing-edge vortex shedding. The main outcomes of this work are a complete fluid mechancial data set for use in development, testing, and validation of high Reynolds number flow models; and insight and understanding of the fluid phenomena that lead to trailing edge vortex shedding.
