The transient density of turbulent flows is calculated by applying large eddy simulation (LES), and the index of refraction for fluid of interceptor is given, which provides data for the study of optical performance of the seeker quantitatively.

• 利用大涡模拟得出湍流瞬态密度值 ,并根据Gladstone Dale关系计算出飞行器周围流场的折射率 ,从而为定量研究导弹导引头光学性能提供依据。
