Research Abstract

本特定領域研究「乱流要素渦による乱流理論・予測・制御の新展開」は,4つの計画研究「乱流要素渦の構造と力学」,「乱流要素渦と組織構造の形成と発達」,「環境乱流の構造と乱流要素渦」,および,「乱流の予測制御と乱流要素渦」で組織されている。本総括班は,領域全体の総括と研究の円滑な推進,および成果の評価を行うのが主な任務である。
1.本特定領域研究に関連する研究集会として,平成13年1月17日〜19日の3日間,京都大学数理解析研究所において,「乱流構造の数理-発生・動力学・統計・応用」を開催し,日本全国から総計70名の参加を得た。本特定領域からは,フランスからの招聘研究員を含み4つの招待講演,そして9つの一般講演を行った。本特定領域以外の研究者による14の講演とともに,活動的な雰囲気の中で,斬新なアイデア,新しい研究結果に大いに刺激を受けた。
2.研究計画班の構成員とは,昨夏から今春にかけて数多く開かれてきた関連研究集会において,顔を合わせるたびに,互いに情報交換を行い,それぞれの班の研究の進捗状況を把握してきた。特に,平成12年10月24日に京都テルサで開催した第1回全体会議,および,平成13年2月23日〜24日にキャンパスプラザ京都において開催した第2回全体会議では,本特定領域研究の研究者ならびに評価委員の先生方のほぼ全員が集い,これまでの研究経過と結果,および今後の研究方針についてつっこんだ議論を行った。
3.本特定領域研究の成果を社会に還元するため,ホームページを立ち上げ,平成12年12月5日から,htp://www.tcsc.nifs.ac.jp/turbulon/なるURLで公開している。
