I am working on the combustion of ammonia, I am facing some issues
1) When I implement Non-premixed combustion, I could visualize combustion but when I try partially premixed combustion I am unable to see combustion. Can someone help me out with the reason/ remedy for the same?
Also, I supplied the laminar burning speeds from detailed 1-D simulations for the partially premixed combustion model.
Thanks and regards,

Is your system premixed or not? You may also need to patch a high temperature region into the zone and a small amount of products to get the calculation started.

Thanks for the message. The system is a non-premixed configuration but since ignition of ammonia takes time, I choose partially premixed combustion model. I did patch progress variable to 1 in the partially premixed model.

If it's non-premixed I'd stick with that approach: premixed is for when the fuel & oxygen enter through the same inlet.
