Research Abstract	アーク加熱風洞の円錐ノズル中の剥離現象を理論と実験で解析し、剥離点が化学反応に依存することを示した。オリフィスから真空中へ膨張する非平衡空気プラズマ流の数値解法を開発し、その構造を解明した。低密度空気の強い衝撃波背後の発光を画像分光法で観測し、時間・波長分解のデータを初めて取得し、分子振動遷移の時間変動的挙動を確認した。化学非平衡を含む完全NS方程式を用い酸素中の強い衝撃波の反射現象を解析すると実験と良く一致した。超音速高温空気流と水素間の混合層反応を素過程から検討し、着火までの過程でOHより酸素原子が重要であることを明らかにした。超音速燃焼エンジンの流れ解析から、境界層の吸込みでインテ-ク内の流れが変化し、エンジン性能に大きく影響することを示した。高速燃焼反応の数値解析において、複雑な境界形状の流れ場と硬い反応速度方程式系を正しく解く手法を開発した。1次元デトネーションの解析から衝撃波と反応面の間を往復する攪乱波がデトネーションの振動的挙動の原因であることを示した。空気過剰の予混合火炎の非平衡領域では、そこに挿入する金属片の温度を制御すれば還元反応で酸化被膜が除去されることを実験的に示した。ベンゼン燃焼のCO_2ガスダイナミックレーザーの出力特性を燃焼条件などで整理し、最適作動条件を得た。準二次元モデルの解析から熱交換型ガスダイナミックレーザーの取出し効率を最大にする条件を検討した。超音速沃素レーザーの数値計算から、凝縮が小信号利得係数などのレーザ特性に与える影響を明らかにした。風洞型エキシマレーザーの高繰り返し運転を進め、出力レーザー光の時間空間的変化を明らかにした。高速度ビデオカメラで超音速噴流を可視化し、その不安定な構造変化を観測して理論予測との乖離原因を突き止めた。振動エネルギ依存解離と弱衝突に基づく反応モデルを提案し、DSMC法で二次元円柱周りの非平衡希薄流を解いた。
