Air Flow Visualization System
Level of Education of Students Involved
I developed an apparatus to visualize pressure gradients in the air. This apparatus is based on the concept of Schlieren imaging. Schlieren being German for streak, as high contrast streaks in the image show the differences in pressure. Key components of the apparatus are an optical zoom camera, point light source, spherical concave mirror, and a knife edge. While the limitations of the usefulness of this apparatus are only constrained by the imagination, the initial application is for visualizing density gradients in the air caused by convective heat transfer. A longer-term goal for the project is to visualize the flow of air through a wind tunnel.
