| Outline of Final Research Achievements |
What should be resolved in the simulations of supersonic jets for the highly-accurate results is investigated using experiments and high-resolution numerical analysis. In the experiments, acoustic, PIV, and Schlieren photograph measurements are conducted and the connections between flow and acoustic fields structures are clarified. In the numerical analysis, the developed high resolution schemes are employed and the details of the aeroacoustic fields are clarified. These results illustrated that the turbulent acoustic waves can be predicted with the sufficiently high accuracy by resolving the transition behavior with the mesh resolution of eight points inside the initial shear layer for the transitional supersonic jet and by resolving the turbulent behavior of initial disturbed shear layer with the mesh resolution of twenty points inside the initial disturbed shear layer and 512 points for azimuthal direction for the disturbed supersonic jet.
