On the workshop in Duisburg we would also like to compare the different models that are frequently used for LII data analysis. Therefore, we provide three data sets of time-resolved LII measurements performed under different conditions. Both, the temporal and spatial laser profile is provided and also the calibration factors for the two-color experiments. The initial temperature of the soot particles after the laser pulse can be analyzed in the way everybody feels most comfortable with.
Each of the files represents a set of two-color data of raw LII signals in excel file format. The files can be downloaded from the website at http://www.vug.uni-duisburg.de/ivg/lii-measurement.html. There are four worksheets in each file. The first two represent the raw data for detection channels 1 and 2, the third is a plot of this data, and the fourth provides the modelling parameters. These parameters include the spatial and temporal profiles of the laser beam, as well as the calibration values for each channel. Note that all of these parameters are different for each data set.
The following should also be noted:
For fairness in the analysis of the data we do not provide more information about the type of flame in which the experiments have been performed.
Everybody is kindly invited to apply his own model for data evaluation. If you have typically use models of different degrees of refinement we would like to encourage you to use all of them. During the meeting in Duisburg we will compare the results which have been calculated with the different models. Additional comparison will be provided with independent measurements. This is an excellent chance for you to test your approach in different measurement situations that might be inaccessible to you usually. For the LII community this is an excellent opportunity to locate typical problems or problematic measurement conditions.
