An IR-camera based particle-tracking technique to measure
free-surface velocity in liquid metal systems
Authors: M. Hvasta, E. Kolemen, A. Fisher
Abstract: Measuring free-surface liquid metal flow
velocity is challenging to do in a reliable and accurate
manner. This paper presents a non-invasive,
easily-calibrated method of measuring the surface velocities of
open-channel liquid metal flows using an IR camera. Unlike
other spatially-limited methods, this IR camera particle tracking
technique provides full field-of-view data that can be used to
better understand open-channel flows and determine surface
boundary conditions. This method could be implemented and
automated for a wide range of liquid metal experiments, even if
they operate at high-temperature or within strong magnetic fields.
