Which combustion model for nuclear power plant?
 

Hello,

I want to compute a hydrogen-combustion in an nuclear reaktor model, but eddy-dissipation, finite-rate eddy dissipation burn to fast and with finite rate the computation isn't working.

Basically I've got two volumes connected with a pipe. In one, there is hydrogen (60% mass-fraction) and nitrogen at 2MPa and in the other is air, steam (30% m-f) and hydrogen (0.4% m-f) at 0.2MPa. And it should ignite on a hot wall at the end of the pipe when the hydrogen comes out (not before).

Does anybody have an idea how this can work?
