Non-premixed combustion: local heat release rate
 

Hi I was was wondering how the local heat release rate is calculated in Fluent??? I know in FDS it is computed by "first locating the flame sheet, then computing the local heat release rate per unit area, and finally distributing this to the grid cells that cut the flame sheet, so the infintesimally thin flame sheet is smeared out over the width of the cell"

Is Fluent the same?

Thanks in advance for your help!

Hi, have you solved the problem? can you please tell me how do you calculate the heat release rate(or define the custom field function) in fluent?

I deeply need the data on the heat release rate!!

sincerely thank you
