Abstract

Hot-film measurements in bubbly flows provide time series that contain information about the liquid and the gas phase. Signal classification is required to disentangle the corresponding segments. The classification algorithms are prone to detection bias, which makes hot-film measurements in two-phase flows very difficult. We present a new phase-sensitive hot-film probe that provides velocity data and optical phase classification in a single device. We report a proof of concept of this method and demonstrate its accuracy and robustness. Furthermore, we discuss its application to turbulent bubbly flows
