temperature rise in combustion simulation

yulia

Hello,

I'm using multiple species model to simulate an internal combustion of the methane-air mixture (Options: volumetric Reaction, Diffusion Energy Source, Finite-Rate reaction model). I get a strange effect of the temperature rise in the core of the flame all the way up to maximum value specified in the Solution Limits panel (whichever value is entered). In all other aspects the solution looks plausible. I would quite appreciate any comments on the problem. Thanks,

Yulia.
