Research Abstract	本研究は、航空・宇宙分野における三次元流の諸問題の特性を、近年進歩の著しい実験的技術と解析・数値シミュレ-ションによって明らかにし、一次元流や二次元流とは本質的に異なる三次元流の問題の解決を図り、あわせて航空機・宇宙機の研究・開発に寄与す幣ことを目的とする。本研究の組織は全国の大学、研究機関に属する25名の研究者によって構成され、次の各項目について分担を決め、研究を進めている。 1.三次元流の基本的性質 (1)渦流、せん断流、噴流、回転流、後流、境界層流、剥離流等 (2)高速流、熱流体、希薄気体流等 2.三次元流の特性 (1)翼まわりの流れ (2)飛翔体まわりの流れ 3.三次元流の計測法の確立 4.解析法の確立と数値シミュレ-ション本年度は3ヶ年にわたる研究期間の初年度にあたり、各研究者の研究を開始するとともに、相互の連絡を密にし、研究会等で討論と情報の交換を行っている。他の研究グル-プと共同で行った2つのシンポジウム(国際宇宙連流体力学シンポジウム、1989年10月、岡山、及び航空・宇宙分野における三次元流の特性に関するシンポジウム、1990年2月、岐阜)において、初年度の研究の成果を検討した。
