Research Content

We investigate the internal flow field and instability phenomena in turbomachinery by using fluid mechanics and computational fluid dynamics (CFD). The basic research on fluid noise caused by the instability phenomena and turbulent flow is also conducted. The other topic is to establish the advanced numerical methods and the new experimental techniques to understand the fluid phenomena. Our research targets are the various industrial machines such as aeroengine and industrial compressors, and electrical appliance blowers. We promote our research in cooperation with the industrial company.

(1) Elucidation of the instability phenomena such as surge and rotating stall that occur in industrial axial and centrifugal compressors

(2) Prediction of fluid noise caused by the unstable phenomena and turbulent flow, and Establishment of the methods to reduce the fluid noise

(3) Establishment and advancement of the numerical analysis methods for turbomachinery

(4) Integration of numerical fluid dynamics and measurement methods, and establishment of new measurement methods

A Brief Comment

The improvement of fluid machinery is always needed, and it is extremely important to understand the mechanism of flow phenomena, because the fluid machinery needs to be more sophisticated. On the other hand, the universities and laboratories of fluid machinery research is decreasing, but Waseda university is the excellent environment where both experimental machines and analysis can be conducted.
We hope that you will actively engage in the research in Waseda's rich environment and gain the ability to play an active role not only at the university but also in society.
