FLEET Velocimetry for Aerodynamics
Annual Review of Fluid Mechanics, 2022 Long-lasting emission from femtosecond excitation of nitrogen-based flows shows promise as a useful mechanism for a molecular tagging velocimetry instrument. The technique, known as femtosecond laser electronic excitation tagging (FLEET), was invented at

The Effect of External Cephalic Version on Fetal Circulation: A Prospective Cohort Study
Children, 2023 External cephalic version (ECV) is a cost-effective and safe treatment option for breech presentation at term. Following ECV, fetal well-being is assessed via a non-stress test (NST). An alternative option to identify signs of fetal compromise is via the

Characterization of the Interaction of Metalworking Fluids with Grinding Wheels
Journal of Manufacturing and Materials Processing, 2022 The thermal load that occurs during grinding can be reduced with the aid of an optimized metalworking fluid (MWF) supply. In previous work, mainly the free jet was considered for the determination of the conditions required for an optimized MWF supply ...

Lorentz Force Velocimetry [PDF]
Physical Review Letters, 2006 We describe a noncontact technique for velocity measurement in electrically conducting fluids. The technique, which we term Lorentz force velocimetry (LFV), is based on exposing the fluid to a magnetic field and measuring the drag force acting upon the magnetic field lines.

Density tagging velocimetry [PDF]
Experiments in Fluids, 2011 Density tagging velocimetry, a novel optical technique for point-wise measurement of flow velocity is proposed here. This new method is based on the detection and subsequent tracking of a local density variation deliberately inserted in the flow. The experimental implementation comprising tagging, detection, and velocity evaluation reverts to and ...

'DefocusTracker': A Modular Toolbox for Defocusing-based, Single-Camera, 3D Particle Tracking
Journal of Open Research Software, 2021 The need for single-camera 3D particle tracking methods is growing, among others, due to the increasing focus in biomedical research often relying on single-plane microscopy imaging.

Extreme measurements with Photonic Doppler Velocimetry (PDV).
Review of Scientific Instruments, 2020 Photonic Doppler Velocimetry (PDV) is a fiber-based diagnostic for the extreme conditions created by high-speed impact, explosive detonation, electrical pulsed power, and intense laser ablation.
