Abstract

In this paper, a newly deduced numerical method is originally applied to solve the complicated transient fluid network in the engine and with that method a new program called UFSSP (Unsteady Fluid Network System Simulation) is developed. As a case study, the UFSSP has been applied to pressurization of a propellant tank, which has been provided a published correlation and numerically predicted by the advanced program in this field called General Fluid System Simulation Program (GFSSP) by NASA's Marshall Space Flight Center (MSFC). Comparisons among the numerical results of the UFSSP, those published data of the GFSSP and the results from the published correlation are presented. It is found that the numerical results of the UFSSP model are in better agreement with the results from the published correlation than those achieved from the GFSSP model. Furthermore, the proposed method leads to an improved computational algorithm and, as a consequence, a significant stability of the computation.
