Time-Resolved Velocimetry Equipment to Transform Realistic Roughness Research
Abstract
The objective is to acquire an array of velocimetry equipment that is flexible enough to enable a range of planar and volumetric particle image velocimetry (PIV) measurements with high spatial and temporal resolution. This equipment, which will interface with an existing high-repetition laser and allow either simultaneous dual-plane stereo PIV measurements or tomographic PIV measurements, will play a central role in a recently-funded AFOSR effort aimed at advancing near-wall models to improve the predictive capabilities of LES for rough-wall flows. The long-term goal is to extend realistic roughness research to the compressible, supersonic and hypersonic regimes, including studying the impact of complex roughness on shock wave/turbulent boundary layer interactions, a critical challenge encountered in advanced propulsion systems. The proposed velocimetry equipment would provide a state-of-the-art measurement system for tackling this critical problem central to the successful design of next-generation AF vehicles.
