FPGA-Mode-Triggered PIV Measurement and Sequential Data Assimilation of Unsteady Flow
A novel online dynamic mode decomposition (DMD) approach using a field-programmable gate array (FPGA), which takes full advantage of the DMD to extract multiple unsteady events and the FPGA system for signal sampling and fast computation, is introduced for phase-locking particle image velocimetry (PIV) measurements of unsteady flow behaviors. For demonstration of this novel approach, the turbulent separated and reattaching flow around a finite blunt plate is examined; high-resolution spatiotemporal evolutions of the dominant flow structures (i.e., the flapping separation bubble, the impinging leading-edge vortex and the trailing-edge vortex street) and their interactive processes are separately assembled. This FPGA-Mode-Triggered PIV setup is also applied to another two configurations, i.e., channel-flow-acoustics resonance (acoustic mode) and flexible membranes (flapping mode) in channel flow. Finally, sequential data assimilation of unsteady flow dynamics is briefly reported, e.g., pressure determination from Tomographic particle image velocimetry measurements of jet flow, turbulent flow and pressure fields over an Aerofoil.

Superresolution Microscopy for Particle Velocimetry
Measurements in micrometer and millimeter-scale flows using optical diagnostic techniques are often hindered by a lack of optical access and spatial resolution limits. This talk will discuss two superresolution imaging techniques, structured illumination microscopy (SIM) and total internal reflection fluorescence microscopy (TIRFM), which can both be implemented in flows with optical access on only one side and have spatial resolutions below classic diffraction limits. SIM is an “optical sectioning” technique that reconstructs a thin slice of an object (e.g. a flow) illuminated over its entire volume by spatially modulated (i.e., structured) illumination from multiple (typically two to five) images. Initial results for SIM-based particle tracking velocimetry in Poiseuille flow indicate that this approach reduces the standard deviation and range of particle velocities by about a factor of two. TIRFM uses evanescent-wave illumination generated by the total internal reflection of light at a refractive index interface, such as that between glass and water, and is therefore inherently limited to visualizing the flow within 1 micron of such interfaces. A number of evanescent-wave illumination-based particle velocimetry studies are reviewed. Both techniques are examples of recent advances in microscopy that exploit novel illumination, vs. imaging, approaches.

Optical Techniques for Unsteady Aerodynamics: From lab application to flight testing
Driven by the increasingly rapid progress of laser, camera and computer technology, several optical techniques used for optical flow diagnostics developed rapidly and did not only offered more potential for lab applications, but were more and more frequently applied in large industrial wind tunnel facilities and during full-scale flight tests. Particle Image Velocimetry (PIV), Background Oriented Schlieren Techniques (BOS) and Differential Infrared Thermography (DIT) and there way up from small scale experiments to aircraft applications in flight will be discussed in more detail.
