Thermodynamic data at extremely high flow velocities pertaining to catalytically stabilized combustion systems with highly conductive materials

The catalytically stabilized combustion system comprises a concentric annular channel, wherein the concentric annular channel further comprises an inner annular channel and an outer annular channel. The concentrically arranged annular channel is 5.0 millimeters in inner channel length, 5.6 millimeters in outer channel length, 0.8 millimeters in innermost diameter, 2.6 millimeters in outermost diameter, 0.1 millimeters in catalyst layer thickness, and 0.2 millimeters in wall thickness.

The spacing between the inner channel and the outer channel is 0.4 millimeters and remains constant. The continuous flow reactor can have any dimension unless restricted by design requirements. All the walls have the same thickness.

One of the potential problems associated with the continuous flow reactor continues to be combustion stability. The maximum Reynolds number is less than 360 at the flow inlet and 960 when the velocity of the flow of the fluid is highest in the channels. The model is implemented in commercially available software FLUENT to obtain the solution of the problem.

Detailed chemistry is included in the model. Detailed chemical mechanisms are playing an increasingly important role in developing chemical kinetics models for combustion. Detailed chemical mechanisms are incorporated into the reacting flow for the continuous flow reactor.

The homogeneous combustion is modeled with the detailed chemical mechanism for methane oxidation in CHEMKIN format. Detailed heterogeneous chemistry in SURFACE-CHEMKIN format is included in the model.
