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.

摘要--CTS-9310542 PI已要求必要的设备来组装基于激光的系统，该系统将用于粒子成像测速（PIV）和平面激光诱导荧光（PLIF）。 该系统应能获得有关火焰-涡流相互作用的基本信息，这些相互作用对火焰应变、燃烧率和熄火有影响，而这些是确定内燃机和快燃发动机循环变化的重要因素。 拟议的系统包括一个脉冲Nd：YAG激光器，染料激光器，和相关的配件，并将使流速的测量，和OH和O-原子密度进行。 该设备将极大地增强目前由NSF资助的密歇根/通用燃烧计划，该计划没有激光诊断的预算。
