抄録(英)
LOX/GCH4 combustion tests of sub-scaled dual-bell nozzle models have been conducted under research collaboration between DLR and JAXA. In this report, RANS simulation corresponding to these experiments was conducted to understand phenomena of the operation mode-transition and to evaluate prediction capability of the mode-transition condition in case with the combusting gas. The results showed that a turbulence model to be used has strong influence on the predicted mode-transition condition and that influence of an oxidizer-fuel mixture ratio on the mode-transition condition was different between CFD and the experiments.
