current research focus

My research aims to attempt engineering contributions, especially for the field of aerospace engineering. My current research focuses on the development of turbulence modeling, passive and active feedback controls of turbulent flows and detailed physical understanding of compressible turbulent flows and its application to aerospace engineering problems using computational fluid dynamics with emphasis on LES/RANS hybrid turbulence methodology. Especially, the following three researches are being promoted now.

---

computational analysis of characteristics of high speed base flows
Characteristics of the cylindrical base flows from subsonic to supersonic speeds are numerically investigated in both the fluctuation and time-averaged aspects with LES/RANS hybrid methodology.

computational study of flow over a maneuvering spheroid with LES/RANS hybrid methodology
Reliability of LES/RANS hybrid methodology for high Reynolds number flows over a pitch-up maneuvering spheroid is investigated. Then, unsteady aerodynamics acting on the body and its turbulence phenomena are also investigated.

LES/RANS hybrid methodology applied to low Re number high speed flows over a wing
Reliability of LES/RANS hybrid methodology for the prediction of Re number effects is investigated. Then, the turbulence phenomena of low Re number high speed flows over an airfoil are revealed.
