The fuel (CH4) and air mixture has an equivalence ratio of 0.8, defined in the Physics Setup. It is injected at T - = 300K with an axial velocity of 50m/s and swirl velocity (Θ direction) of 30m/s. The air inflow is at T = 650K and is injected at 10m/s axially, with no swirl. This case is axisymmetric and so the physical combustion chamber is assumed to be cylindrical; rotated about the axis of symmetry. The outflow is the pressure outlet at atmospheric pressure.
