Lorentz Force Velocimetry

Author(s): A. Thess, E. V. Votyakov, and Y. Kolesnikov
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. Two series of measurement…
