Abstract
Development of a stereoscopic particle image velocimeter for the measurement of three-dimensional vectors on a planar domain is described. The camera is based on two large format (2k × 2k) video cameras. Experiments in a turbulent boundary layer at Re θ = 2525 demonstrate its ability to measure three-dimensional turbulent flow. In addition to the quantitative value of the out-of-plane component, it is found that having the complete three-dimensional vector also significantly improves the qualitative visualization of the flow.
