Abstract :The present study aims at considering applicability of the constant current method as the measurement method of void fraction in a bubbly flow through a Venturi nozzle, which can be used to generate fine bubbles recently. For the accurate measurement of void fraction using this method, it is essential to identify the cause of havingthe a negative value of void fraction. The experimental result of a single bubble through the nozzle showed that the void fraction becomes negative when the bubble contacts with one electrode and do not contact with the other electrode, whilst the void fraction correctly becomes positive when it contacts with the both electrodes or do not contact with the both.
