Default Combustion methane-air
Posts: n/a
Hi !

I'm trying to compute a methane-air combustion of a premixed system. Methane and air are introduced in a small tube, conneted to a combustion chamber at 0.5 Mpa, by a swirl injector. My main parameters are :


Pressure based, Axisymmetric Swirl, steady.


Species transport, Volumetric Reaction, Finite-Rate/eddy-Dissipation, Mixture = methane-air

---Operating Conditions

Op. pressure = 500 000 Mpa

---Boundary Conditions

Inlet : velocity inlet. Outlet : pressure outlet (=0 Pa)


turb. kinetic energy 0.04455. turb diss. rate 0.506

The problem is that my results are not the same as the ones presented in a paper with the same computation, concerning pressure especially.

First of all, is there any parameter that seems not correct ?

Thanks a lot for your help
