Assuming incompressible Newtonian fluid with constant properties, the steady equations of continuity, momentum and energy have been solved simultaneously by using the finite volume method under constant heat-flux condition. Momentum thickness Reynolds number at upstream boundary is 76 and both with and without artificial disturbance are tried. Growth of disturbance, spanwise pitch of streamwise vortices and interference between adjacent vortices are examined based on the velocity vector and vorticity maps. Mechanism of successive induction of vortices is explained by using buoyant production of streamwise vorticity., 資料番号: AA0047776014, レポート番号: JAXA-SP-04-002}, pages = {45--46}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {不安定成層下におけるロールセル対流について}, volume = {JAXA-SP-04-002}, year = {2005} }
