Temperature correlation velocimetry technique in liquid metals

The article describes the temperature cross-correlation velocimetry method applied to liquid metal flows. The technique allows to measure temperature waveforms and average longitudinal velocity in a flow simultaneously. The used micro thermocouple sensor and signal processing procedure are described in comparison with other works where the same or a similar approach have been implemented. Examples of experimental results obtained in MPEI1 - JIHT2 mercury facilities, are also provided. Method has been successfully used in magnetic fields up to 1 T.
