Applications
PIV has been applied to a wide range of flow problems, varying from the flow over an aircraft wing in a wind tunnel to vortex formation in prosthetic heart valves. 3-Dimensional techniques have been sought to analyze turbulent flow and jets.
Rudimentary PIV algorithms based on cross-correlation can be implemented in a matter of hours, while more sophisticated algorithms may require a significant investment of time. Several open source implementations are available including Fluere (Cross-platform GUI in C++), URAPIV and mpiv (a MATLAB Toolbox), PyPIV (an implementation in Python), JPIV (a Java implementation), OSIV and Gpiv (both implementations in C).
Application of PIV in the US education system has been limited due to high price and safety concerns of industrial research grade PIV systems. As part of the National Science Foundation (NSF) project, Educational PIV (e-PIV) system is used in teaching fluid mechanics to students studying fluid mechanics in design, engineering and science including physiology.
