Outline of Research at the Start

壁に沿う乱流場の核心的構造である「渦」の生成・発達・消滅過程を含むライフサイクルを,新たに導出した渦構造の輸送方程式を用いて定量的に解明する.さらに,摩擦抵抗低減を目的とした各種の乱流制御手法が渦の時間応答性に与える影響を定量的に明らかにする.渦の輸送方程式を用いることで,従来勘案できなかった渦の時間発展に着目し,高効率な壁乱流制御手法を確立する.

Outline of Final Research Achievements

Life cycle of vortices, which are core structures of wall turbulence, was quantitatively elucidated including generation, development, and decay processes using a newly derived transport equation for vortical structures. Specifically, direct numerical simulations of turbulent channel flow were performed using a high-resolution spectral method, and the characteristics of each term in the transport equation were clarified. Furthermore, by using the vortex transport equation, we focused on the temporal evolution of vortices, which could not be taken into account in the past, and developed a more efficient turbulence control law.

Academic Significance and Societal Importance of the Research Achievements

本研究では,壁乱流の中核的構造である渦の生成・発達・消滅過程を定量的に世界で初めて明らかにし,渦構造の普遍的知見を得た.新規に導出した渦の輸送方程式は,抵抗低減を目的とした乱流制御に留まらず,渦に関連する全ての流体現象に応用が可能である.即ち剥離や流れ構造の制御,流体力の制御,騒音低減,伝熱・拡散制御,反応制御などにも適用でき,新技術開発,環境問題軽減に貢献できる.
