Engineering Research Equipment Grant: High Speed Motion Analysis System

所要求的设备将由三个实验室共用。 这些实验室中的每一个都在先进激光的使用方面表现出色 在各自的领域进行诊断。 他们工作的一个共同主题是 使用激光片的光散射来确定结构 的火焰和流场，分别。 由于速度低， 目前的相机系统，只有单镜头实验或非常缓慢的流动 是可能的。 有了自旋物理相机， 内燃机中的紊流火焰、三维的 气体射流中的浓度场和速度场， 液体流动由于其高速度而可以全部被研究。 该系统 还具有优于传统电影摄影机的优点， 获得定量的数字数据。 获得的结果将 对了解发动机的燃烧、流场、 结构和混合过程。

The equipment requested is to be shared between three laboratories. Each of these laboratories is prominent in the use of advanced laser diagnostics in their respective fields. A common theme of their work is the use of light scattering from laser sheets to determine the structure of flames and flow field, respectively. Due to the low speed of the present camera system, only single-shot experiments or very slow flows have been possible. With the Spin Physics Camera, the evolution of turbulent flames in internal combustion engines, three-dimensional concentration and velocity fields in gaseous jets, and mixing studies in liquid flows may all be studied due to its high speed. This system possesses also the advantage over conventional movie cameras that quantitative, digital data is obtained. The results obtained will be invaluable to the understanding of engine combustion, flow field structure, and mixing processes.
