In small gas turbine engines, the boundary layer separation-reattachment phenomena on low pressure turbine blade surfaces are strongly affected by the upstream wakes at low Reynolds number conditions (O is approximately 10(exp 5)). It is well known t

Publikováno v: 航空宇宙技術研究所特別資料: 航空宇宙数値シミュレーション技術シンポジウム2002論文集 = Special Publication of National Aerospace Laboratory: Proceedings of Aerospace Numerical Simulation Symposium 2002. 57:232-237

Recently, CFD analyses have been extensively applied to noise reduction technologies of a supersonic transport engine. This paper introduces the CFD activities for noise reduction technologies. For fan noise, the magnitude of unsteady pressure on the
