It can be found that foci (corresponding to A1 and A4 in Table 1) dominate the flame zone when P = 0, which means rotation dominates the flow field with zero dilatation. Considering that the incompressible characteristics play an important role in the whole flame zone (as seen in Figure 5), rotation is the representative flow pattern in the distorted flame zone.
