Hi all,

I am doing a catalytic combustion in a micro-channel. My problem is I can not get ignited results. Namely with iteration going on, the reaction zone would move out of the channel and temperature in the whole computation domain finally goes to room temperature.

A lot of efforts have been done to solve the problem mainly focused on surface mechanism. However, nothing succeed.

I am thinking there are great possibilities that something of my fluent model is wrong. But I don't know what is it.

I can not attach any files in this thread. Can anybody help me to check the model please? I can sent you all the case, mechanism, thermo and transport files to your email.
Best.

Weiqiang.
