Comparison of burning velocity differences in a numerical explosion simulator
Abstract
A verification study of the two flame models in the numerical explosion simulation tool FLACS has been conducted. The beta flame model, and the SIF flame model has been tested in a 1D-channel at different time step sizes. Methods for measuring the flame speed has been discussed, and a best practice method has been chosen. The 1D-channel has been tested for closed end ignition and open end ignition. The possible introduction of a Fourier number as a stability criteria is also discussed.
