| Outline of Final Research Achievements |
SLAU2(Kitamura-Shima, 2013), one of numerical methods for compressible flows, has been investigated first in high-speed (hypersonic) flows. It has been discovered that, if SLAU2 is used with a strong limiter function (which degrades spatial accuracy at a shock wave), "shock anomalous solutions" are suppressed, and prediction accuracy of aerodynamic heating is enhanced.
Then, with a "two-fluid modeling," SLAU2 were successfully applied to multiphase flows that covers wide-ranging flow speeds from low-speed to high-speed.
