低速热射流剪切层光学性质主动控制研究
Active Optical Control for Low Velocity Heated Jet Shear Layer
摘要
分别对稳定、基波和亚谐波周期扰动入口边界条件的二维欧拉方程进行了数值模拟,得出了射流剪切层中大涡结构的空间演化特征,计算了不同入口边界条件时的流向斯特列尔比,从而提出了对流场进行主动控制的光学意义.
Abstract
The two-dimensional Euler equation with steady,fundamental frequency and first subharmonic frequency inlet boundary conditions is solved.The development of large-scale structures in the heated jet shear layer is numerical simulated.And the streamwise far field time averaged strehl ratio is calculated at different inlet boundary conditions.The optical significances of actively flowfield control are presented.
