Modeling Fire, Part 2 – Heat Release Rate

In this video, we discuss what it means to define a fire using the Heat Release Rate. When we specify a Heat Release Rate, we are really specifying the rate at which fuel is released into the fire simulation. The fuel mass flow rate is calculated so that combustion will release heat at the desired rate.

We show how to use the stoichiometric reaction calculations in a spreadsheet, and how to verify that FDS is using the same calculation.
