Abstract

This paper describes a new design of a local four-sensor
probe which was used to measure the local velocity vector
of the dispersed phase in a bubbly gas-liquid two phase
flow. Based on the four-sensor probe signals, a new signal
processing technique was also introduced. Reference data
was obtained using high speed cameras to determine the
optimum value for the threshold voltages relevant to the
output signals from the four sensors on the probe. Groups of
signals from the four sensors that were generated by the
same bubble were identified but the signals from some
bubbles were ignored by the signal processing scheme.
After using the signal processing technique, the results have
been improved compared with the results without the signal
processing technique.
