Figure 5.6: Evolution of Maximum Temperature for Spatially Fixed Ignition. The maximum
temperature T max is plotted against time t considering the whole computational
domain. Heat introduction is performed at r m,in = 0.8×10 −3 m.

Figure 5.7: Evolution of Maximum Temperature for Spatially Variable Ignition. The maximum
temperature T max is depicted as in Figure 5.6 but based on the ignition
method with a variable heat introduction r m,in at φ r = 0.5.
