Three-Dimensional Imaging Towards Three-Dimensional Velocity
Introduction Particle Image Velocimetry has become a widely used quantitative flow visualization technique in today’s fluid mechanics research due to its ability to provide non-intrusive, highly resolved measurement of planar velocity fields. With the use of ever-advancing CCD cameras, digital data acquisition systems, and sophisticated algorithms, DPIV continues to evolve and flourish. One of the key advancements is the development of Three-Dimensional Defocusing Particle Image Velocimetry (3DDPIV , which allows for three-dimensional velocity measurements within a volume. Technology description Researchers at the University of Washington have invented a three-dimensional imaging system designed to allow for measurements of velocity within a volume using a single lense and camera system. The images from the lense can be recorded in any way, either using a photographic system or a digital image recording system. Software is then used to post-process images, to get the data to a point that would allow for further processing using previously established software. Business opportunity This technology is suitable for visualizing and quantifying micro-scale fluid flows. This research has tremendous potential to benefit society by impacting energy conservation efforts and development of energy efficient devices. New knowledge of turbulent convective flow physics can lead to the ability to accurately predict them through proper LES modeling. Furthermore, our research can help reduce industry costs by permitting analyses to be conducted numerically rather than experimentally. In an ever increasing energy conscious society, this will result in more efficient devices (i.e. heat exchangers and combustors , ultimately saving in energy costs.Type of Offer: Licensing
