Sources of error in PIV will be summarized and classified according to whether they are random or bias errors, flow-dependent or flow-independent and single-particle or multi-particle. Single particle errors can be analyzed by considering the case of one particle, but they are also inherent to the case of multiple particles. Multi-particle errors occur when statistical methods such as spatial correlation are used to extract the correct image pairings between exposures. The limits of spatial and velocity resolution will be discussed in terms of these classifications. The goal is to provide a background to explain the steps needed to create a new generation of PIV instruments having greatly extending dynamic range, accuracy and spatial resolution.
Introduction of Speakers：
Dr. Adrian is the Ira A. Fulton Professor of Mechanical and Aerospace Engineering in the School of Mechanical, Aerospace, Chemical and Materials Engineering at Arizona State University. Prior to joining ASU in 2005, Dr. Adrian was a faculty member in the Theoretical and Applied Mechanics Department at the University of Illinois at Urbana-Champaign. Dr. Adrian's research interests are the space-time structure of turbulent fluid motion in wall flows and the study of unsteady shocks using ultra high speed optical methods. Techniques to which he has made fundamental contributions include laser Doppler velocimetry, particle image velocimetry, and the optimal estimation method for analysis of turbulent flows. Dr. Adrian has authored over 175 publications in archival journals and book chapters, and he has edited or co-edited 12 books on experimental fluid mechanics. Dr. Adrian is a member of the United States National Academy of
Engineering and a Fellow of the American Physical Society, the America Institute of Aeronautics and Astronautics, the American Society of Mechanical Engineers, and the American Academy of Mechanics. His awards include the 2001 Nusseldt-Reynolds Prize for experimental fluid mechanics research, the 2002 AIAA Aerospace Measurement Technology Award for his role in developing the particle image velocimeter, the 2005 Fluid Dynamics Prize from the American Physical Society, the 2007 Fluid Dynamics Award given by the American Institute of Aeronautics and Astronautics, and the 2009 Fluids Engineering Award given by the American society of Mechanical Engineers. He is listed by ISI Web of Science as one of the 250 Most Highly Cited Researchers in Engineering, 2005.
