Development of a system for void fraction measuring by electroprobing method

An analysis of a variety of techniques to measure local values of void fractions using electric probes inserted in flow has been carried out. The main factors restricting the application of these techniques and sources of measurement errors are established. It is demonstrated that the uncertainties are primarily due to inaccurate algorithms defining the fluid phase. A description of the system developed and eliminating the elucidated shortcoming has been presented. 12 refs.; 3 figs
