Default Problem using EDM for combustion

Hi,

I am trying to simulate combustion in a cylindrical pipe using Eddy Dissipation Model. At the inlet and outlet of the pipe I have made "far-field" domains as the flow around the inlet and outlet is also important.

The boundaries of "far-field" are assigned with ambient pressure and temperature and zero velocity.

In this setup, I am not being able to initiate combustion. I have solved the flow-field (cold flow analysis) but when I switch ON the reaction, no product formation occurs.

I am simulating a completely unsteady problem. I think there is some problem with EDM setup as I got acceptable flow-field from cold flow simulation.

Please Help.
