Optical Phase Detection Probes and Instrumentation- Optical phase detection probes can be used to measure air concentration (void fraction), inter-facial bubble velocity, bubble chord length, and time histories of these quantities.
- Laboratory model scale, and prototype full scale
- Flow velocity range 0.25m/s – 35+m/s, limited only by probe surviving debris strikes
