Webcan be very helpful when the equivalence-ratio is close to the flammability limit. Note that the mixing zone width is larger than the initial domain. This is fine as these parameters have relatively little physical meaning, but we find that more spread-out guesses are often more likely to lead to convergence than narrow ones. WebSep 3, 2024 · What Does Lower Flammability Limit (LFL) Mean? Lower flammability limit (LFL) refers to the lower limit of the gaseous or vaporized fuel, combustible material or dust’s concentration in the air, at a fixed temperature and pressure, which can lead to flame propagation, detonation or an explosion. Weblower ﬂammable limit. Hence when the ﬂash point is known, it is easy to use vapour press-ure data from the literature6,7 to determine the vapour concentration by partial pressure.
