Shock phenomena caused by a rapid valve closure in a slug flow region were investigated. The experiment was conducted in a horizontal acrylic tube of 20.7 mm ID, 4.85 mm in thickness, and 18.5 m in length. The profiles of the transient pressure caused by a rapid valve closure in slug flow are affected by the flow configuration adjacent to the valve, and these are classified into two types according to the existence of a gas slug or a liquid slug at the valve at the instant of valve closure. The characteristics of the transient pressure in the former were analyzed by an oscillation system model composed of a mass (liquid slug) and a compressible capacity (gas slug). Those in the latter were also analyzed for a homogeneous two-phase flow model by a similar method to that in a waterhammer analysis. The experimental results were well explained by these analyses.
