Webb10 sep. 2024 · In the following, a long and stable period was observed that was dominated by ablation. Another reversal of flow was found about 2 ms before CZ: With decreasing arc current, the wall ablation and thus the pressure in the nozzle decreased to values below that in the heating volume. WebbIf a plume-dominated fire evolves to create its own storm activity, it becomes self-sustaining unless forces outside the plume change. Lightning can start new fires kilometres ahead of the main fire front. Spot fires are also likely to break out as embers are swept up in the swirling winds.
