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.

'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.

Post-processing methods of PIV instantaneous flow fields for unsteady flows in turbomachines [PDF]
, 2012 The Particle Image Velocimetry is undoubtedly one of the most important technique in Fluid-dynamics since it allows to obtain a direct and instantaneous visualization of the flow field in a non-intrusive way.

Sensors, 2016 Optical feedback interferometry (OFI) is a compact sensing technique with recent implementation for flow measurements in microchannels. We propose implementing OFI for the analysis at the microscale of multiphase flows starting with the case of parallel ...

The dependence of speckle contrast on velocity: a numerical study
Journal of the European Optical Society-Rapid Publications, 2022 We study how the speckle contrast depends on scatterer velocity, with the goal of further developing laser speckle imaging as a quantitative measurement technique. To that end, we perform interferometric computer simulations on a dilute plug flow.

Development of a Hot-Wire Probe with Two Parallel Wires Placed Closely Together
Journal of Fluid Science and Technology, 2009 We manufactured a new hot-wire probe with two parallel wires placed closely together for measuring a transitional boundary-layer flow. The main feature of this new probe is that it is much smaller than a conventional multi-sensor probe, such as an X-type

Flow rate measurement in aggressive conductive fluids
EPJ Web of Conferences, 2014 Two non-contact experimental methods of flow rate measurements for aggressive conductive liquids are described. The techniques are based on electromagnetic forces and Faraday’s law: Lorentz force is induced inside moving conductive liquid under influence

Single camera three component planar velocity measurements, using two frequency Planar Doppler Velocimetry (2v-PDV) (2005) [PDF]
, 2005 The work presented here describes a method that allows three component velocity measurements to be made, quickly and non-intrusively, across a plane in a flow defined by a laser light sheet. The method, two frequency planar Doppler Velocimetry (2v-PDV)
