Boltenko, E. Boltenko] The review of probing methods of two-phase flows is presented. Methods of electrical, optical, acoustical, and thermal probing are considered and their main errors are determined. It is shown that when determining the true local volume void fraction φL by the probing method of the flow, the errors that are small can be decreased via increasing the measurement duration and the frequency of the supplying voltage. The procedure is presented, based on which, the selection of the optimal (relatively minimal error) of the true volume void fraction is possible. The use of the suggested procedure makes it possible to increase the accuracy of determining φL and to improve the representativeness of the data. Advantages and disadvantages of the methods of optical probing and acoustic probing compared with electrical probing are considered. The method of thermal probing is described. When implementing it, the thermocouple junction is used, which is heated by passing the alternate current. Block diagrams of thermocouple probes and the procedure of determining the true volume void fraction using the thermal probing procedure are determined.
