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. WebOne hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas is at its lower flammable limit. The relationship between percent LEL and percent by volume differs from gas to gas. The example below demonstrates the flammability of Methane (Natural Gas) in Air.
