Abstract
Water hammer phenomena of two-phase bubbly flow caused by a rapid valve closure in a 90° bend pipe were investigated experimentally. The experiments were conducted in a horizontal tube of 25.4mm in inner diameter and 1.9~3.8 in ratio of the curvature radius to the inner diameter of the bend tube, in the ranges of superficial velocity from 0.23 to 1.64 m/s and of void fraction from 0. 0% to 1.12%. The air and water were used as the working fluid. The value of potential surge and its attenuation, and propagation velocity of the compression waves were obtained and discussed, comparing them with those in the single-phase water flow. The distribution of potential surge in a 90° bend pipe is a "ring", and it was respect with void fraction, superficial velocity, curvature radius.
