Flammable Gas Volume Fraction Variable

New “Flammable Gas Volume Fraction, %LFL” post-processing variable as of version 1.39, which shows the flammable concentration and can be used to compare multiple cases even when those cases use different flammable gases.

  • As an example, if you have only one simulation with one inflow of Methane then the Flammable Gas Volume Fraction, %LFL would be the same as the Methane Volume Fraction. However, if the simulation has one inflow of pure Methane and one of pure Ethane, this variable would combine all the flammable components which would provide the overall reading from a hydrocarbon flammable gas detector.

  • This variable is also useful if you have many simulations all with different, but flammable fluids. This would be a common variable between all of them so risk data sets can be made for gas detector optimizations.
