Schubring D, Shedd TA, Hurlburt ET, et al., International Journal of Multiphase Flow 36 (5): 385-396 May 2010. Velocity and frequency increase with liquid and gas flow rates, length decreases with increasing gas flow and increases with increasing liquid flow, and intermittency is predominantly an increasing function of liquid flow.
Schubring D, Foster RE, Rodriguez DJ, et al., Measurement Science and Technology 20 (5): article #065401 Jun 2009. Micro-scale particle imaging velocimetry (micro-PIV) has been applied to 20 two-phase air-water flows in the wavy regime and near the wavy/annular regime transition. Velocity profiles and fluctuation statistics have been calculated based on the particle image pairs produced, which were divided into base film and wave zones. A linear velocity profile is seen within the base film that extends farther from the wall than in turbulent single-phase channel flow.
Schubring D, Shedd TA, International Journal of Multiphase Flow 35 (4): 389-397 Apr 2009. It is found that the trends in base film thickness measurement do not match trends in the literature for average film thickness, which considers waves and base film together. Keywords: Liquid Film; Flow; Critical Film Flow Rate.
Arias DA, Shedd TA, Journal of Fluids Engineering-Transactions of the ASME 129 (9): 1193-1202 Sep 2007. A commercial computational fluid dynamics (CFD) package was used to develop a three-dimensional, fully turbulent model of the compressible flow across a complex-geometry venturi, such as those typically found in small engine carburetors. The results of the CFD simulations were used to understand the effect of the different obstacles in the flow on the overall discharge coefficient and the static pressure at the tip of the fuel tube.
