• 11015 Estimation of two-phase flow regime with flow noise

抄録

Estimation of two-phase flow regime was studied by using sound data which were from the flow through vertical pipe made of acrylic. The sound data was classified into four flow regime based on the video data, and analyzed. We found that two-phase flow is able to be classified into two kinds that the flow containing large amount gas flow or not, by using frequency spectrum analysis of flow sound data. And we found specific feature on the flow containing relatively large amount gas flow by using auditory roughness which is one of the methods of psychoacoustic sound quality evaluation.
