Particle tracing is a simple technique used to infer global quantitative information regarding velocity and vorticity fields from flow images. In this paper, recent advances in solving major drawbacks associated with conventional particle tracing are discussed. A quantitative automatic scheme which eliminates the photographic step and is capable of constructing the velocity field directly from the experimental set up is presented.

Additional Information:© 1988 by Morteza Gharib. Published by the American Institute of Aeronautics and Astronautics, Inc. An initiation grant from the Engineering Foundation (GR Engng Fdn RI-A-86-7) has been instrumental in the development of the automatic particle tracing technique described in this paper. Currently a grant from DARPA/ACMP is supporting us in efforts to add the three-dimensional and multifield capability to the technique. Many colleagues and former students have helped us in bringing the technique to its present stage. We would like to thank Dr. Miguel Hernan for helping with the initial development of the idea, Barry Dyne and Oran Thomas for helping in the development of software, Thomas Phillips and Chee Yap for different stages of hardware development and Dr. Kathie Stuber for her careful laser doppler measurements.
