Volumetric measurements of a self-similar adverse pressure gradient turbulent boundary layer using single-camera light-field particle image velocimetry

Z Zhao, AJ Buchner, C Atkinson, S Shi, J Soria - Experiments in Fluids, 2019 - Springer
As a novel volumetric particle image velocimetry technique, single-camera light-field PIV (LF-
PIV) is able to acquire three-dimensional flow fields through a single camera. Compared
with other multi-camera 3D PIV techniques, LF-PIV has distinct advantages, including
concise hardware setup and low optical access requirements. Its capability has proven
effective in many experimental investigations. In this study, the use of LF-PIV in measuring a
self-similar adverse pressure-gradient turbulent boundary layer (APG-TBL) is demonstrated …

The structure and dynamics of adverse pressure gradient turbulent boundary layers (APG-
TBL) have a significant role in the efficiency and performance of a range of transportation
and energy generation platforms. This is particularly true in regions of strong adverse
streamwise pressure gradient, such as near the trailing edges of wings and turbine blades,
where separation of the boundary layer can significantly reduce performance with the
potential for catastrophic consequences. The optimal design of such systems remains …
