Research Abstract	二原子分子の解離・再結合反応が分子の振動・回転エネルギ,自由電子エネルギに与える影響を定量的に求め,これを再突入物体の衝撃層計算に適用してその影響を明らかにした.アーク加熱空気流の低密度膨張流を多温度モデルで解析し,分子種により温度分布がかなり異なることを示した.アーク加熱風洞でアルゴン電離気体を測定し,物体上流の暗領域の発生原因を明らかにいした.強い衝撃波背後の発光を二次元観測して,その形態の特性と放射強度分布が従来の理論では十分説明できないことを示した.完全ナビエ・ストークス方程式を用いて衝撃波の反射パターンを計算し,高マッハ数では凍結流計算と異なることを示した.衝撃波管の測定部における衝撃波のマッハ反射とマッハステムの三次元的干渉を数値的に明らかにした.またラム加速機の有限速度化学反応の影響を明らかにし,従来の理論を発展させた.水素-メタン混合燃料における着火時間を求め,メタン混合率で三段階に分類できることを示した.超音速燃焼エンジンインレットにおいて,衝撃波-境界層干渉場を数値的に明らかにした.また,超音速・極超音速流に対する効率の良い計算法を提案した.ラム加速機の改良を進めた.定常デトネーションの不安的機構を数値解析し,デトネーションの安定性は反応機構の条件に依存することを明らかにした.多段式ノズルを用いてベンゼン燃焼のCO_2気体力学レーザーの性能向上を図ったが余り効果のないことが判った.気体力学レーザーに対して,マイケルソン干渉計で超音速自由渦空力窓の光学特性を明らかにした.風洞型レーザーの連続・高繰り返し運転が出力レーザー光の時間的空間的変化に与える影響を実験的に明らかにした.固体壁面での気体分子の運動を分子動力学でシミュレートし,従来の拡散反射境界条件の妥当性を検討した.低密度・高圧超音速ジェットの構造を分子運動論でシミュレーションすることにより,DSMC法による予測が可能であると判った.
