摘要 　通过建立物理模型,求解层流N S方程,用数值方法模拟了二维热射流流场的有序大涡结构,计算了流场不同流向位置的光程值,分析了射流流场混合层的光学特性,得出了气动光学流场由于流场中大尺度涡结构的存在所引起的光学不均匀性,大涡结构中奇点所导致的光学畸变最大,在一定条件下大涡结构有散焦作用。 Two dimensional laminar flow N-S equations are solved to simulate the large scale vortical structures in heated jet flow field, and the optics path lengths at different streamwise positions were computed. The results indicated that the features of the vortical structure induced different optical aberration. Because of the existence of the large scale vortical structures the optical inhomogeneity of turbulent flowfield was educed.
