This paper introduces the CFD activities for noise reduction technologies. For fan noise, the magnitude of unsteady pressure on the 3D stator vane evaluated through a use of unsteady 3D stage analysis. For jet noise, Large Eddy Simulation (LES) is applied to prediction of exhaust jet mixing of a lobed mixer nozzle. It is confirmed that a CFD application takes an important role in noise reduction technologies., 資料番号: AA0045948041, レポート番号: NAL SP-57}, pages = {232--237}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {超音速輸送機用エンジン低騒音化技術への数値流体解析の適用}, volume = {57}, year = {2003} }
