Experimental flow visualization is a valuable tool for analyzing microfluidics and nanofluidics
in a wide variety of applications. Since the late 1990s, considerable advances in optical …

We use structured monochromatic volume illumination with spatially varying intensity
profiles, to achieve 3D intensity particle tracking velocimetry using a single video camera …

The two-year effort to reactivate Von Kármán Facility Tunnel D, funded by the Air Force
Research Laboratory High Speed Systems Division, reintroduces a valuable ground-test …

RainbowPIV is a recent imaging technology, proposed for time-resolved 3D-3C fluid velocity
measurement using a single RGB camera. It dramatically simplifies hardware setup and …

Fluid velocity measurement in liquid films is a challenging task due to the small film
thickness and large transverse gradients of velocity. While this problem was solved for the …

Flow evolution over helicopter rotors, wind turbine blades, and insect wings are unsteady,
three-dimensional (3D), and influenced by phenomena unique to the rotating frame of …

This work demonstrates the capability of a high speed camera as a detector for focused
laser differential interferometry (FLDI) a cylindrical lens setup. To test the system's capability …

The video-capabilities of smartphones are rapidly improving both in pixel resolution and
frame-rates. Herein we use four smartphones in the “slow-mo” option to perform time …

The objectives of this study were to provide time-resolved (1) characterizations of shock
wave/transitional boundary layer interactions using schlieren flow visualization, and (2) …

NE of the limiting factors in the design of supersonic and hypersonic vehicles remains the
prediction and control of the high aerodynamic, thermal, acoustic, and structural loads …
