초록
A numerical study has been performed to investigate 1-D steady/unsteady start-up characteristics for liquid rocket engines using SINDA/FLUINT. First, in order to verify the analysis of cryogenic fluid, RL-10 engine having expander cycle is selected as a target of present study. Pressure drop in cooling channels was simulated through orifice devices. Satisfactory agreement has been obtained through the comparison of the numerical analysis and the experimental results. Based on these results, a start-up analysis of RD-8 having staged combustion cycle has been performed. As comparison of the numerical analysis and the experimental results, tendency of start-up characteristics had good agreements. This methodology of present study will be able to be used for the analysis of liquid rocket engines as a future work.
