The model is based on Boeing 767 aircraft having two aisles in a wide body. In the model, interiors (i.e. ceilings, side wall, seats, and floor) and human bodies are taken into account. To deal with the complicated geometry of flow field efficiently, this model consists of Large Eddy Simulation (LES) based on Smagorinsky Model (SM) and is using IBM (Immersed Boundary Method) to adopt uniform staggered grids. The flow velocities at the immersed boundary cells are determined according to the volumetric fraction of solid. The effect of buoyancy is treated by Boussinesq approximation. The profiles of temperature and oxygen concentration are also calculated simultaneously. It is shown that the process is reproduced successfully for our purpose of optimizing cabin air quality., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064672031, レポート番号: JAXA-SP-09-011}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {埋め込み境界法を用いた機内空気流のLESの構築}, volume = {JAXA-SP-09-011}, year = {2010} }
