Clemens CTS-9553124建议的工作集中在用平面激光诊断学研究湍流/火焰和湍流/扩散相互作用的基础上。湍流/反应区相互作用、平面提升火焰中的稳定机制以及湍流中的微分扩散将成为研究的目标。这些研究将利用激光成像的流场变量，如速度，OH和CH自由基浓度，以及燃料喷射浓度。速度将使用粒子图像测速仪(PIV)测量，物种浓度将使用平面激光诱导荧光(PLIV)测量。重点将放在多个流动变量的同时成像，如速度和OH(或CH)，或具有不同质量扩散系数的两个标量。将提供的信息对于发展和验证寻求预测燃烧效率和大气污染物水平的湍流反应流动模型将是重要的。

Abstract Clemens CTS-9553124 The proposed effort centers on the fundamental studies of turbulence/flame and turbulence/diffusion interactions using planar laser diagnostics. Turbulence/reaction zone interactions, stabilization mechanisms in planar lifted flames, and differential diffusion in turbulent flows will be targeted for investigation. The studies will make use of laser imaging of flow field variables such as velocity, OH and CH radical concentrations, and fuel jet concentrations. Velocities will be measured using particle image velicometry (PIV) and species concentration using planar laser-induced fluorescence (PLIV). An emphasis will be placed on the simultaneous imaging of multiple flow variables such as velocity and OH (or CH), or two scalars with different mass diffusivities. Information will be forthcoming which will be important for the development and validation of turbulent reacting flow models which seek to predict combustion efficiency and atmospheric pollutant levels.
