摘要
本文给出了飞机增升装置气动力特性的数值计算方法和计算结果。为了计算增升装置的缝隙效应和剪刀口效应 ,求解了粘性三维Navier Stokes方程。为了正确模拟大舵偏和阻力板后的大面积分离 ,采用了反映涡流特性的新类型的两方程湍流模型。
This paper presents the numerical simulation method and calculation results for the flow around a high lift devices of airplane. In order to compute the effects of slots for high lift devices, the 3 D Reynolds averaged incompressible Navier Stokes equations are solved numerically by using a finite volume method.A new type of two equation turbulence model ,in which the local vorticiy of the main flow is introduced to close the turbulence stress,is suggested to simulate the large area separations for high deflenction and for air brake.
