Figure 5.8: Evolution of Weighted NO x Production for Spatially Fixed Ignition. Figure 5.6
shows the profile of the corresponding maximum temperature T max . Here, the
NO x production rate ˙ω NOx is normalized with the molar mass of NO 2 .

Figure 5.9: Evolution of Weighted NO x Production for Spatially Variable Ignition. Figure 5.7
shows the associated profile of T max . In line with Figure 5.8, the NO x production
rate ˙ω NOx is normalized with the molar mass of NO 2 .
