4038 縦渦による流れの剥離制御(G05-8 境界層・はく離,G05 流体工学)  [in Japanese] 4038 Control of Flow Separation by means of Streamwise Vortices  [in Japanese]

The FBG cantilever sensor was used for detection of flow separation. This optical sensor detects a shift of the wavelength to the reflected light corresponding to the amount of strain. We had researched on the sensing of direction to flows. As a next stage, this sensor was installed at trailing edge of a aerofoil, and has investigated on the performance of the sensor and the characteristics of the flow separation. As a result, this sensor could catch the changing of the flow direction to the flow separation.
