IEEE Xplore – Long-Duration Time-Resolved PIV to Study Unsteady Aerodynamics.

 

If you’re after unsteady fluid dynamics processes that last longer than ten Kolmogorov time scale units (most of the processes do, besides the viscous tilting we’re been working on for some time or turbulent entrainment across a thin interface) then you need to stream and store your data. We solved it two ways: long-duration streaming and/or real-time image processing (see Kreizer and Liberzon, Exp. Fluids, 2010)
