Abstract :
The fuzzy set theory and the flow-imaging technique were applied to measure the flow pattern and void fraction of two-phase flow. The flow pattern was identified online by using `fuzzy identification´, and an instrument system based on the flow-imaging technique was developed for online flow pattern measurement as well. The void fraction was evaluated online by `fuzzy multifactorial evaluation´. The void fraction was also measured online by an instrument system based on the flow-imaging technique. The experimental results show that the developed methods are satisfactory
