In this paper a method to identify flow regime is reported in order to give a fundamental insight into air-magnetic fluid two-phase flow. The flow regime classification is based on the magnetic induction method of void fraction measurement. The proposed method identifies the flow regimes by waveforms of induced electromotive force. In experiment, we obtained induced electromotive force in actual two-phase flow by adopting volumetric flux of each phase as a main parameter. In order to confirm the flow regime, flow-regime visualization was carried out. The relationship between flow regime and the corresponding waveform of the induced electromotive force was investigated. As a result, the waveforms of electromotive force can be categorized, as in the case of flow regime, into waveforms corresponding to bubbly, slug, churn and annular flows. Moreover, the signal of induced electromotive force was treated by a signal processing with wavelet transform to obtain a probability density function (PDF).
