Web11 de mar. de 2024 · Learn how to deal with and prevent recurrence of fungal tulip fire in our expert guide. Fungal spores attack emerging tulip leaves. They invariably become malformed, with brown spots leading to rotting of both the foliage and flowers, although the buds may well fail to open. If they do open, there will probably be white spots on the petals. WebThe numerical results show that both ignition methods and thermal boundary conditions affect flame formation and its shape. The flame keeps a single tulip shape in the whole process of propagating through the channel if plane ignition is used and a single mushroom shape if spark ignition is used.
