摘要
计算流动显示是近年来在流体力学领域出现的一个新的研究方向 ,是计算流体力学、实验流体力学和科学计算可视化等领域的结合。本文介绍了其概念和原理 ,描述了一种简单高效的基于光线投射方法的光线跟踪方法 ,用于构造计算流场的干涉图、阴影图和纹影图 ,并给出了计算与实验结果的比较。
Computational flow imaging(CFI)is a new field of research in computational flow dynamics.It combines computational and experimental flow dynamics,together with visualization techniques.In this paper,we describe the basic conception and principle of CFI,and propose a new and efficient method of ray tracing,which stems from raycasting in the flow field.The computational results of interferomgram,schlieren and shadowgraph generated are shown and compared with experimental images.
