Kids Definition. flashback. noun. flash· back ˈflash-ˌbak . 1: the introduction of a past event into a story or motion picture. WebMechanical flame arrestors are filled with metal or ceramic, which absorbs heat from a flashback, quenching it to a temperature below what is needed for ignition. This stops the flame. With a low enough hydrocarbon/air mixture flow rate, if a flame travels to the face of the arrestor, it can become stable at that point.

WebJan 1, 2024 · We have shown in Ref. [1] that near flashback, the contribution from flame curvature dominates the total stretch rate while near blow-off, stretch is caused by both flow strain and flame curvature. Another question that arises is related to the difference between flames with merged and separated leading edges. Two examples are shown in Fig. 1 for …
