No Combustion with reactingFOAM

Tobi Wehr · February 17, 2020, 03:23

Hello, everybody,

i have been working with reactingFoam (the latest OpenFOAM version) for some time now. I've watched the tutorial SandiaD_LTS. For my own simulation and geometry I used this tutorial as a basis.
I also have an inlet for air, an inlet for fuel and also an inlet for pilot. The problem I have is that there is still no combustion. Because of the high temperatures at the interface between the pilot and the fuel-air flow, I expect a temperature increase. But nothing of the same happens to me.

In the beginning you can still see that other species are created by a reaction. But later the number of iterations for this is 0.

Have any of you had this problem before and can you give me a hint or help me?

Thanks a lot!

Greeting

Tobi
