ABSTRACT--CTS-9310996 The proposal is for equipment that would allow simultaneous Raman scattering measurements and OH fluorescence imaging on turbulent jet flames to be carried out. The equipment consists of a back-lit CCD camera, a lens coupled intensifier, and associated hardware. The camera will allow instantaneous imaging of the important chemical species and structure of the turbulent reaction zones leading to a better understanding of the effects of dissipation rate and flame curvature on the finite-rate chemistry occurring in these flames. This new camera can enhance the Raman detection limits sensitivity and measurement accuracy over the old ICCD camera presently available. The old camera will be used for the OH (PLIF) fluorescence imaging measurements.

摘要：CTS-9310996提议的设备将允许同时进行拉曼散射测量和OH荧光成像湍流射流火焰。该设备由背光CCD相机、透镜耦合增强器和相关硬件组成。相机将允许重要的化学物质和湍流反应区结构的瞬时成像，从而更好地理解耗散率和火焰曲率对这些火焰中发生的有限速率化学的影响。与现有的旧ICCD相机相比，这种新型相机可以提高拉曼检测极限的灵敏度和测量精度。旧相机将用于OH （PLIF）荧光成像测量。
