ENGINEERING RESEARCH EQUIPMENT: Laser Flowfield Diagnostics for Ongoing Michigan/G.M. Joint Combustion Research

摘要-CTS-9310542国际和平研究所要求组装一个基于激光的系统，该系统将用于粒子成像测速和平面激光诱导荧光。该系统应该能够获得关于火焰-涡流相互作用的基本信息，这些相互作用导致对火焰应变、燃速和消光的影响，这些都是决定内燃机和快燃发动机循环间变化的重要因素。该系统包括一台脉冲的Nd：YAG激光器、染料激光器和相关的附件，并将能够测量流动速度以及OH和O-原子密度。该设备将极大地增强目前由NSF资助的密歇根/通用汽车燃烧计划，该计划没有预算激光诊断。

ABSTRACT--CTS-9310542 The PI has requested the necessary equipment to assemble a laser based system that will be used for particle imaging velocimetry (PIV) and planar laser-induced fluorescence (PLIF). This system should be capable of obtaining fundamental information on flame-vortex interactions leading to effects on flame strain, burn-rate, and extinction which are important factors in determining cycle-to-cycle variations in IC and fast-burn engines. The proposed system includes a pulsed Nd:YAG laser, dye laser, and associated accessories and would enable measurements of flow velocities, and OH and O-atom densities to be made. The equipment will greatly enhance the current Michigan/GM combustion program that is funded by NSF for which no laser diagnostics were budgeted.
