A concave parallel plate capacitance sensor has been developed to measure the two-phase flow void fraction for the purpose of objectively identifying flow regimes. The sensor has been used in conjunciton with a two-phase flow loop on board the NASA Lewis DC-9 micogravity aircraft, and data was recently collected. The void fraction time trace and probaility density function, along with high-speed video images of the flow were used to determine a more objective method of flow regime identification than is possible through examination of video images alone.
