Description
Shadowgraph and schlieren imaging are popular flow visualization techniques because, despite the straightforward setup and reliance on very simple geometrical optics principles, they provide powerful methods for capturing high-quality images of what would otherwise be invisible flow phenomena. Application of these methods along with high-speed video recording can reveal detailed pictures of fast flow events that may last for just a fraction of a millisecond. These techniques are being utilized in the Bethel Fluid Mechanics lab course (PHY423/ENR423) and in a number of student-faculty research projects. We present snapshots of a few recent student-faculty projects utilizing shadowgraph and schlieren imaging.
