Hi Gandolf:

Without seeing the setup, it is difficult to answer this question.  It looks like the temperature was initialized to 800 and then influenced by colder inlet stream (possibly intake air?), before increasing again due to combustion.  I would try post-processing the run at different points to understand the cause.

Best Regards,

Judy
