Determination of Single Component Velocities in Two-Phase Flow Systems Using Correlation Methods

The determination of single-component flow velocities is significant in steady-state and transient water vapor-droplet flow systems. The method presented here treats local random vapor density variations and statistically varying droplet concentrations as uncorrelated processes. Signals are generated by simultaneous light absorption and scattering measurements. By applying an adapted correlation technique, gas and droplet velocities within two-phase flows can be determined separately
