Research Abstract

理論研究では、乱流と構造形成の非線形機構の解明の中心課題である微視的揺動・メゾスケール及び巨視的構造の共存状態の理論研究を体系化する成果を上げた。「ミクロな乱流揺動はメゾスケール場を誘起しその非線形相互作用も含め乱流の状態が定まる」という新しい物理的描像が体系化された。定量的な理論結果として、メゾスケールの場とミクロな乱流場が共存する状況での輸送係数や二次元界面構造の表式を得るなど多くの成果を上げた。また、非平衡統計力学によるプラズマ乱流統計理論の基盤の吟味をまとめ上げた。天体現象にも成果を上げ、太陽の磁流構造の研究成果をモノグラフ"Solar Tachocline"(Cambridge 2007)の一章に論述した。
シミュレーションでは、多スケール結合を研究するための新しいコード開発を推進した。トーラスプラズマについて、乱流揺動の機構を明らかにし、乱流輸送の理論式を検定した。更に微視的な乱流揺動の発展によって巨視的な磁気流体力学不安定性の成長率が強い影響を受けることも見出し、異なるスケールの揺動が共存するプラズマの新たな構造形成過程を見出した。直線プラズマ実験の設計原理や解析を先導するための「数値直線プラズマ(numerical linear device:NLD)」を開発し、ストリーマー構造の実験的発見を先導する等の成果を上げた。
実験ではトロイダルプラズマを対象に乱流場や構造相転移の直接観測を行い、帯状流および帯状磁場の双方を発見した。乱流と帯状流の非線形結合強度を定量的に実測し理論と比較することに成功した。詳細な観測をするための直線プラズマ実験も多チャンネル(プローブ・データ収集系)高分解能計測が進みストリーマー構造の実験的発見を成遂げた。
