An upgraded Laser Doppler Velocimeter (LDV) will be used in studies of deposition processes in optical fiber manufacturing, vortex dynamics in rectangular combustors, flame structure for combustion chemistry studies, and atomization processes in liquid rocket motors. The upgraded instrument will be capable of measuring velocity from zero to +- 200 m/sec under a variety of conditions. For the deposition study, particle velocities will be measured under the influence of electric field enhanced deposition conditions for comparison with modeling calculations. In the asymmetric combustor study, velocity distributions will be measured in a rectangular dump combustor with acoustic forcing. In the combustion chemistry studies, velocities normal to the test burner will be measured to aid in determining kinetic behavior. In the atomization study, liquid drop size and velocity distributions under oscillationing flow conditions will be measured. Acquisition of the upgraded equipment will lead to a more quantitative assessment of a variety of combustion process, and should positively impact the optical fiber, jet engine, and rocket motor industries.

升级后的激光多普勒测速仪 (LDV) 将用于研究光纤制造中的沉积过程、矩形燃烧室中的涡流动力学、燃烧化学研究中的火焰结构以及液体火箭发动机中的雾化过程。 升级后的仪器将能够在各种条件下测量从零到+/- 200 m/s 的速度。 对于沉积研究，将在电场增强沉积条件的影响下测量粒子速度，以便与建模计算进行比较。 在不对称燃烧室研究中，将在具有声学强迫的矩形转储燃烧室中测量速度分布。 在燃烧化学研究中，将测量测试燃烧器的法线速度，以帮助确定动力学行为。 在雾化研究中，将测量振荡流条件下的液滴尺寸和速度分布。 购买升级后的设备将对各种燃烧过程进行更加定量的评估，并对光纤、喷气发动机和火箭发动机行业产生积极影响。
