WebThe Flammable Range(also called Explosive Range) is the concentration range of a gas or vapor that will burn (or explode) if an ignition source is introduced. Three basic … 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.

WebAug 8, 2024 · Flammability Limits (LFL, UFL) Autoignition Temperature (AIT) - Sustained burning (sometimes referred to as sustained combustibility or Fire Point) is the lowest temperature at which the vapors produced above the liquid surface will continue to burn once ignited – not just create a flash fire. WebFlammability limit refers to the upper or lower limits of the gaseous or vaporized fuel or combustible material at a fixed temperature and pressure that can lead to flame propagation, detonation or an explosion. Fuel or combustible concentrations outside the both limits are considered to be non-flammable. Safeopedia Explains Flammability Limit
