| Outline of Final Research Achievements |
The numerical and experimental studies on the cryogenic flow under the transcritical and supercritical pressures are performed in order to understand the thermodynamic characteristics and fluid dynamics. The coaxial cryogenic nitrogen jet flows under the supercritical pressure are simulated using ILES/RANS hybrid method. The mean inner jet lengths of the present simulations agree well with those of the previous experiments and numerical simulations. As for the multi-species flow simulations, the numerical method using a hybrid method between the energy equation and pressure-evolution-equation, which is able to prevent from pressure oscillations in the flow, is developed. In the experiments, visualization data and temperature profiles in the cryogenic nitrogen channel flow are measured under the subcritical and supercritical pressures.
