Flow regime discrimination technique for gas-liquid two-phase flow in magnetic fluid

摘要

This paper describes a new discrimination technique of flow regime (flow pattern) for gas-liquid two-phase flow in magnetic fluid. The proposed technique can identify the flow regime with simple devices by exploiting the wave patterns of signals obtained by electromagnetic induction. This utilization achieves a mechanically non-contact measuring method for objective fluids. In this study, verification experiments for practical measurement were conducted in upward gas-liquid two-phase flow. The results of the experiments have verified that the proposed measuring technique is useful as a method for flow regime discrimination.
