Outline of Research at the Start

本研究では,超音速噴流の超時空間解像計測を行いその音響波発生メカニズムの解明を行う.ここで超時空間解像とは解像度の異なる2種類の計測から時間方向にも空間方向にも高解像度の結果を推定することである. 具体的には以下の項目を実施する.1.解像度の異なる2種類の計測法による同時計測の実験データ取得する,2.低次元モデルによる超時空間解像結果の推定する,3.データ駆動統計モデルの構築による音響波発生メカニズムの解明を行う.これらの3つの項目を海外共同研究者の協力を得て実施する.

Outline of Final Research Achievements

In collaboration with Prof. Tim Colonius of the California Institute of Technology (Caltech), we developed a spatio-temporal resolution measurement algorithm and applied it to supersonic flow measurements, enabling the estimation of spatiotemporally resolved measurement results of supersonic flows that overcome the limits of conventional measurements. In particular, by using Fourier series expansion to perform hyperspace-resolving measurements, we have succeeded in recovering a three-dimensional velocity field even from a two-dimensional PIV measurement. In addition, we were able to propose a framework for ultra-spatial-resolution measurement that takes into account the dynamics and to recover turbulent structures that are weakly correlated with the microphone.

Academic Significance and Societal Importance of the Research Achievements

本研究課題では,海外渡航先で共同研究を行うことで,これまで計測できなかった超音速機などがつくる極限流れをデータ駆動科学を利用して,超時空間解像された流れ場を推定する方法を開発した.これまでに計測できなかった極限流れを計測できるようにすることで,先進の航空機や列車,自動車などの輸送機の開発に活きる技術となると考えられる.
