Abstract
A study on the character of pressure wave propagation was proposed for the gas liquid oxygen two-phase flow in the pipe between pumps. According to the practical working conditions, the homogenous model based on the compressibility theory regarding a single bubble in an infinite liquid, and Redlich-Kwong gas equation was derived a model for the low temperature and high pressure case, especially considering the change of the ratio of density of gas to one of liquid. The numerical tests were conducted. The results not only show the agreement between numerical simulation for this model and experiment at the normal temperature and pressure is good, but also show that the modifications of the model for the low temperature and high pressure condition are necessary. The study is of reference to further study of oscillation restrain and relative pipe tests.
