Outline of Final Research Achievements

At the forefront of aircraft development, the target of aerodynamic design is shifting to unsteady phenomena that occur at the boundaries of the flight boundaries, such as stall and buffet. In this research, an integrated visualization method capable of measuring two-dimensional distribution of time-varying surface-pressure and shear-stress fields with high resolution and high accuracy has been developed as an experimental tool that can be used universally for unsteady aerodynamic design of aircraft. For pressure field measurements, we succeeded in capturing fluctuations with the Pa order magnitude and in the kHz order frequencies using advanced noise-reduction techniques such as SVD. For the shear-stress field measurements, we developed a visualization method using the principle of optical flow and confirmed its accuracy and robustness through carefully-designed verification tests. We prepared for a release of these measurement techniques as general-purpose visualization tools.

Academic Significance and Societal Importance of the Research Achievements

本研究によって,境界層の剥離と再付着,はく離渦の放出とその崩壊,それらの相互干渉による非定常空気力の発生メカニズムの理解と解明に道が拓ける.さらには,はく離や空気抵抗の能動的な流体制御デバイスのより系統的な設計が可能になる.本研究の成果は非定常空力設計に利用できるツールとして整備し公開する準備を進めており,最終的には,航空機の効率化や他分野(自動車,高速鉄道,タービン機器など)への波及を通じて,流体工学の発展と応用に貢献するものである.
