Fluid Imaging GraphDevelopment and Implementation of Advanced Fluid Imaging Diagnostics

To further develop Defocusing Digital Particle Image Velocimetry (DDPIV) methodology, we have derived a full three-dimensional characterization of Defocusing Digital Particle Image Velocimetry and have overcome the limitations of the single camera DDPIV system, by developing a color-coded backlighted system. Furthermore, we have extended this approach by developing a novel 3D particle tracking velocimetry (3DPTV) that identifies overlapped particles, thereby allowing for increased spatial resolution

Display Case At a Glance SketchVertical Display Case Air Curtain Optimization

This collaborative effort between UW, Kettering University, and Southern California Edison, is to study air curtains, their entrainments, and their infiltration as applied to vertical open display cases, which are commonly found in supermarket stores nationwide. The goal is to ascertain the conditions that would minimize ambient warm air infiltration into the vertical display cases, so as to minimize the energy consumption of the display cases. As vertical display cases are used nationwide, we will therefore be able to reduce the national energy burden in this area. Click image for larger view.
