Determination of temperature and concentration gradients in technical combustion systems using pure rotational CARS

这项研究提案计划作为DFG研究项目的延伸。该项目的目的是进一步开发旋转CARS技术，即使在测量体积中存在强烈的温度和浓度梯度的情况下也可以使用该技术。这一拟议项目是基于DFG研究项目SE804/4-1所取得的成果。将进一步开发受温度和浓度梯度影响的光谱的CARS计算程序，以减少评估大量实验光谱所需的计算机时间。这对于对湍流火焰中采集的数据进行统计分析是必要的。为了检验和验证所开发的评价程序的实际应用，将在湍流扩散火焰中测量受温度和浓度梯度影响的旋转CARS光谱。

This research proposal is planned as a prolongation of the DFG research project. The aim of this project is to further develop the rotational CARS technique that it can be used even in situations where strong temperature and concentration gradients are present in the measurement volume. This proposed project is based on the results achieved in the DFG research project Se 804/4-1. The CARS calculation program for spectra influenced by temperature and concentration gradients will be further developed to reduce the necessary computer time for the evaluation of large amounts of experimental spectra. This is necessary for a statistical analysis of data taken in turbulent flames. In order to test and demonstrated the practical use of the developed evaluation routine experimental rotational CARS spectra influence by temperature and concentration gradients will be measured in turbulent diffusion flames.
