Burned mass calculation

[TasKall67]

Hi there,

I have a case in which there is a release of flammable liquid (or gas). I have added a surface that blows 500kg of the species in the domain in 4 seconds. I have assumed that the species (e.g. benzene) has low Auto Ignition Temperature (0) and burns immediately when enters the domain. I would like to measure how much of that mass is finally burned out. What kind of DEVC can i use to get that results in time interval and the total? Or, is reliable to divide the total heat release with the heat of combustion to get the burned mass?

Yes, integrating the heat release rate and dividing by the heat of combustion will tell you how much fuel burned inside your domain.

Thank you for the direct reply.
