Abstract Dual-tip phase-detection intrusive probes are the most widely used experimental technique for measuring interfacial velocities in highly aerated flows. Recently, we have introduced an adaptive window cross-correlation (AWCC) technique, which allows for the estimation of pseudo-instantaneous velocities and associated velocity statistics. Several potential limitations of this technique were suggested by Chanson (2020). In a direct response, the AWCC is clarified and shortcomings of conventional signal processing as well as general limitations of dual-tip phase-detection probes for velocity measurements are discussed. A comparison and validation of the AWCC against event detection techniques, image-based velocimetry and stochastic signals demonstrates the method’s novel opportunities for air–water flow research.
