| Abstract: | At the time of waiting for launching instruction, two - phase flow water-hammer in rocket pipe system are introduced which is caused by geyser phenomena. The two-phase flow water-hammer was simulated by a discrete vapor evaporated and condensed model. The method of characteristic was used. Th e results provided a basis for safety analysis of low temperature propellant sys tem in rockets. |
