Abstract
The objective of this thesis was to expand the accumulated knowledge ln the field of two-phase flow of saturated water through pipes. The effect which a varying pipe length-to-diameter ratio, in the range of 10 to 160 (diameter equal to 0.275 inches), has on the flow characteristics was investigated. The slip ratio or relative velocity between the vapor and liquid phases and the velocity of the vapor phase were determined for a steady critical flow condition. Also, due to a suspected fallacy in the value of the slip ratio obtained by Croteau, Reference 3, a reevaluation or his data was accomplished. This experimental investigation was conducted utilizing the test equipment and instrumentation used by Croteau with the addition of a 11-tube, 60-inch mercury manometer bank and a Model 900 Polaroid Land Camera to obtain pressure profiles along the length of the test pipes.
