Coaxial injection of hydrogen-nitrogen at supercritical conditions
| Summary: | Transcritical and supercritical coaxial injection is modelled for a nitrogen-hydrogen coaxial configuration characteristic of the conditions present in liquid rocket engines, with a central high-density low-velocity nitrogen jet and a low-density high-velocity hydrogen jet. Multispecies modelling follows an incompressible variable density approach which demonstrates itself as a valid alternative to the commonly fully compressible formulations encountered in the literature. The results show agreement with the experimental data and compressible formulation in terms of the species radial density profiles maximum values. |
