Dear Ember Users
I am trying to use Ember to simulate a cylindrical outlwardly propagating flame.
(The flame propagates away from axisymmetric axis without straining effect along the flame surface).
For the detailed configuration, please check the attached file.
I am following the example_cylindrical_outward.py, and setting the strain rate to 0.
(I believe by doing this the flame could propagate prependicularly to the unburnt gas, exactly like the outwardly propagating flame.)
The code runs, but the results seems incorrect as the burning velocity overestimated the laminar burning velocity. (Fig.1)
I have checked the simulation results at each time steps, and I found the flame temperature increased over the adiabatic flame temperature as flame propagating. (Fig.2)
The combustion seems intensified, and thus the burning velocity become larger (than the laminar burning velocity).
Since I have not found relative configurations, I wonder whether what I am doing is correct or not.
Regards,
Cui
