Abstract

Abstract: In order to study the case that propellant remains in the intracavity of pipeline connector after orbital refueling, the twophase unsteady model of volume of fluid (VOF) is used to simulate the gasliquid flow field during the blowing-off process. The pressure distribution has little range of vibration in the straight pipeline at the initial blowing-off process. There is an eddystyle flow field and the eddy brings the residual propellant from the intracavity of pipeline connector into the straight pipeline, which is the main mechanism of the residue blowing-off process. The results show that most of the residual propellant in the intra-cavity of pipeline connector can be blew out, and prove the fine effect of the blowing-off process.

Key words: liquid propellant, orbital refueling, pipeline connector, blowing-off
