Long-lasting emission from femtosecond excitation of nitrogen-based flows shows promise as a useful mechanism for molecular tagging velocimetry instrument. The technique, known laser electronic (FLEET), was invented at Princeton decade ago and has quickly been adopted used in variety high-speed ground test flow facilities. short temporal scales offered by amplifiers permit nonresonant multiphot...

Aerodynamics of trucks and other high sided vehicles is of significant interest in reducing road side accidents due to wind loading and in improving fuel economy. Recognizing the limitations of conventional wind tunnel testing, considerable efforts have been invested in the last decade to study vehicle aerodynamics computationally. In this paper, a three-dimensional near field flow analysis has...

By applying tension asymmetries in a finite-element model of vocal fold vibration, a variety of modes of phonation were simulated. The biophysical model incorporated tissue mechanics, glottal aerodynamics, and acoustics of the vocal tract. For simplicity and speed, glottal aerodynamics were modeled with a modified Bernoulli equation. Vocal tract acoustics were modeled using a wave reflection an...
