Synchrotron x-ray fluorescence has been used to measure temperatures in optically dense gases where traditional methods would fail. These data provide a benchmark for stringent tests of computational fluid dynamics models for complex systems where physical and chemical processes are intimately linked. The experiments measured krypton number densities in a sooting, atmospheric pressure, nonpremixed coflow flame that is widely used in combustion research. The experiments not only form targets for the models, but the simulations also identify potential sources of uncertainties in the measurements, allowing for future improvements.
同步辐射X射线荧光已被用于测量传统方法无法适用的光密气体中的温度。这些数据为对物理和化学过程紧密相连的复杂系统的计算流体动力学模型进行严格测试提供了基准。实验测量了一种广泛用于燃烧研究的、有烟灰生成的常压非预混并流火焰中的氪数密度。这些实验不仅为模型提供了目标,而且模拟还识别出测量中潜在的不确定来源,以便未来改进。
