| Abstract: | Void fraction is one of the fundamental quautities necessary to describe the flow characteristics of two-phase mixture; yet it remains one of the most elusive to measureIn this paper, the global void fraction measurement of a two-phase flow in the pipe of circular cross section was discussed, including the principle of measurement, sensor structure, exciting field, etc. The optimized condition of sensor structure was given. A reference sensor was used for measuring the conductivity of liquid so as to compensate its effects. |
