Abstract: The study of two-phase flows has formed the basis of several industrial applications. The analysis of the concentration gradient of the two phases and the transformation of a particular flow pattern to another has played a vital role in estimating the durability of the machinery used in industries. For efficient analysis of the flow characteristics, one needs to obtain experimental data depicting bubble size, velocity of the bubbles. This paper reviews a time trace method to measure the bubble diameter and velocity in a two-phase gas-liquid flow using a conductance probe. A comparative study on the design of the probe electrodes has been done and an appropriate geometrical design of the probe electrodes has been mentioned. This paper also presents the electronic circuit development of the probe. The principle of the experiment revolves around the difference in electrical conductivity of the two-phases and the corresponding voltage changes noted when each phase is in contact with the probe electrode. The output signal is finally analyzed by an oscilloscope. In addition a few experimental results in regard with the transition of flow pattern and gaseous phase concentration are analyzed. Also an appropriate design of probe electrodes has been selected at the end.
