ABSTRACT Proposal Number: CTS-9870993 Principal Investigator: W. Lempert, M. Samimy Funds are awarded to develop a high speed diagnostic imaging system which will provide the capability to study the dynamic behavior of time evolving and three dimensional flow fields. The instrumentation will consist of a high power solid state "burst mode" laser and a companion digital CCD framing camera. The laser system will be tunable in the mid-infrared, visible, and ultraviolet region of the spectrum and will be capable of generating pulses with a minimum interpulse period of 1 microsecond. The system will be used to study the influence of streamwise vorticity on acoustic noise suppression, physics of large scale mixing in complex, three dimensional flows, anomalous shock wave propagation and dispersion in weakly ionized plasma, and the creation and sustaining of atmospheric pressure volumetric plasmas. The system will also be incorporated into a two quarter electromagnetics laboratory sequence, "Atoms, molecules, electromagnetics, and information."

项目编号：CTS-9870993项目负责人：W. Lempert， M. Samimy获资助开发一种高速诊断成像系统，该系统将提供研究时间演化和三维流场动态行为的能力。该仪器将包括一个高功率固态“突发模式”激光器和一个配套的数字CCD分幅相机。激光系统将在光谱的中红外、可见光和紫外线区域进行调谐，并将能够产生脉冲间隔时间最小为1微秒的脉冲。该系统将用于研究顺流涡度对噪声抑制的影响、复杂三维流动中大规模混合的物理特性、弱电离等离子体中异常激波的传播和色散，以及大气压体积等离子体的产生和维持。该系统还将被纳入两个四分之一的电磁学实验室序列，“原子、分子、电磁学和信息”。
