【摘要】 本文采用Menter等发展的基于局部变量的γ-Reθt湍流转捩模式对平板和NLR7301翼型开展了转捩模式验证工作,进而对带有前、后缘襟翼的多段机翼流动转捩进行了数值模拟.研究结果表明,转捩对于多段机翼的气动特性具有较大影响,数值模拟可为多段机翼中襟翼偏角、间距等设计提供有益指导.更多还原

【Abstract】 Transition simulation of plane,named as T3A/T3B,and NLR7301 multi-element airfoil were presented in this article as verification case for the transition model proposed by Menter & Langtry.Furthermore,the transition past high-lift wing with leading edge and trailing edge flaps was investigated using fully turbulence model and transition model.Results indicated that transition had an important affect on the aerodynamic characteristics of high-lift wing.The simulation could provide suggestion for disign of high-lift wing,especially the selection of the gap between main wing and flap and the deflection angle of second flap.更多还原
