Cross-consistency of system and characteristic-field models in a coupled liquid-rocket simulation (Merlin 1D–class case study)

Abstract: Coupled liquid-rocket system models and multidimensional nozzle solvers are usually developed separately; when they are made to share a chamber state, the mass-flow consistency between them is easy to leave unmeasured. We describe a transient LOX/RP-1 open-cycle gas-gen...
