i try to simulate laminar premixed burner with infinte-rate model, but i can not ignition through patch high temperature
Can someone give me advice

Dear Florent
My simulation object is a tube laminar premixed burner, to simulate laminar combustion velocity, as in chapter 3 in article “A computational study of two dimensional laminar premixed combustion of methane and some biofuels”.
Boundary condition and models:
Velocity Inlet is 0.5 m/s, natural and air equivalent ratio is 1, such as ch4 is 0.095, o2 is 0.19;
Tube wall is adiabatic;
Tube diameter is 0.025 m, tube length is 0.05m;
Out is pressure out conditions;
Solver is pressure solver, 2D axisymmetric;
Flow is laminar;
Species transport is used, volumetric reaction, infinite rate model and stiff chemistry solver are selected.
My simulation procedures are follows:
1. a non-reacting fuel oxidizer mixture is simulated through the tube
2. adapt a region at x=0.005-0.015, y=0.-0.0125
3. patch this region, temperature is 2200k
But no reaction accrues.
How to patch?
If you has not that article, i can give you. you cangive you email
