Flame stabilization(DNS)
Hello to all of you. I am new in the CFD community and this is my first attemp to contact you. I hope you can help me. I want to find informations about stabilization of a flame in a mesh. This is my exact problem :I have a flame which is at first fixed in position. For an unknown reason the flame starts to move towards reactants.So the flame sheet moves to regions, where I use a low resolution scheme.I want to avoid something like this. I have read that I can add an additional term in the continuity equation, in order to avoid such a flame displacement.I can not find in bibliography books or papers reffering to this part (how to add this additional term on my DNS scheme or something like that). The code is DNS.I think there is a different approach on LES.Can you help me or sent me references about it. Thank you all in advance.
