Eshwar is on a distinguished road
I am using a partially premixed combustion model with a secondary fuel inlet.
I have two fuels one is the main high velocity jet fuel and the other is a pilot fuel to stabilize the jet.

Whatever I do I am unable to start the reaction between the reactants.

I have done a high temperature patch even tried a flame stabilizing geometry.
Nothing seems to work.

Kindly give me some suggestions on how to ignite the flame ...
