摘要
为实现室内湍流模拟,本文尝试通过研究平均流场、湍流流场及其合成气动光学效应,利用Zernike模式法计算相位,得到随机相位分布的数学模型。根据该模型,采用掩模移动光刻技术,制作随机位相板。通过控制位相板的运动,实现了湍流扰动的等效模拟。
To realize turbulent simulation in lab, this paper attempts to study the average of flow field, Turbulent flow field and Pneumatic optical effects , use Zernike mode method to calculate the phase ,and get the mathematical model of the random phase distribution. According to the model, we use the mask exposure mobile photolithography method to make random phase plate. Through controlling the movement of phase plate, we realize the equivalent simulation of the turbulence.
