Evaluation of Comprehensive Models
In order to be used with confidence for quantitative purposes, such as combustor design, comprehensive models must be rigorously evaluated. It is generally the case that model subcomponents have been evaluated through comparison with measurements. This often takes the form of curve fitting of experimental data to provide model coefficients. Figure 3.8 and 3.10 illustrated comparisons of correlative methods and data for devolatilization. Figures 4.5 and 4.6 illustrated similar comparisons for char reaction rates. While such comparisons are vital in establishing the reliability of model components, they are insufficient in assessing the accuracy of the comprehensive codes that combine several model elements.
