The upward flow of oil-water-air and oil-water mixtures in a .75 inch I.D. tube is investigated. Flow pattern, volume fraction, and pressure loss data is presented for mixture velocities from 4 to 20 ftsec and oil in liquid volume fraction from 0 to 1.0. The drift flux method of Zuber and Findley is successfully extended from two phase flow to three phase flow in order to predict the air void while a new correlation method is presented to estimate the In Situ oil phase volume fraction. In addition, the oil-water flow regime-map of Govier is extended to three phase flow in order to predict the transition between liquid flow regimes. Finally several friction pressure loss prediction methods from two phase flow are modified to three phase flow and compared to actual data. As a result, a scheme of several methods is recommended for use in preparing three phase flow pressure loss estimates. Author
