      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.
