Abstract
Water hammer phenomena caused by a rapid Valve closure, that is, shock phen omena in two-phase flows, are an important problem for the safety assessmen t of a hypothetical LOCA. This paper presents the results of experimental a nd analytical studies of the water hammer phenomena in a one-component two- phase bubbly flow. In order to clarify the characteristics of water hammer phenomena, experiments for a one-component two-phase flow of Freon R-113 we re conducted and a numerical simulation of pressure transients was develope d. An overall picture of the water hammer phenomena in a one-component two- phase flow is presented and discussed.
