The safe, clean, and reliable operation of combustion devices depends to a large degree on
the exact control of the fuel/air mixing process prior to ignition. Therefore, quantitative …

Long-lasting emission from femtosecond excitation of nitrogen-based flows shows promise
as a useful mechanism for a molecular tagging velocimetry instrument. The technique …

Time-accurate velocity measurements in unseeded air are made by tagging nitrogen with a
femtosecond-duration laser pulse and monitoring the displacement of the molecules with a …

Advances in microfluidic and nanofluidic technologies have been paralleled by advances in
methods for direct optical measurement of transport phenomena on these scales. A variety …

The application of acetone-based molecular tagging velocimetry (MTV) is demonstrated in
sonic and supersonic jets produced by a 1-mm-exit-diameter nozzle. Measurements are …

This manuscript describes the wide variety of optical measurement techniques for
characterizing the flow in hypersonic wind tunnels. The introduction briefly describes …

Molecular Tagging Velocimetry (MTV) is a whole field optical technique that relies on
molecules that can be turned into long lifetime tracers upon excitation by photons of …

In this work, we present the excitation/emission strategy, experimental setup, and results of
an implementation of krypton tagging velocimetry (KTV). KTV is performed as follows:(i) …

Following three decades of research in short duration facilities, Purdue University has
developed an alternative turbine facility in view of the modern technology in computational …

Femtosecond laser electronic excitation tagging (FLEET) is a nonintrusive optical diagnostic
technique that has been demonstrated to provide direct measurement of velocity and other …
