Reaction heat

Laci · July 8, 2009, 06:06

Hi everybody,

I try to simulate a tank, where oxygen and carbon-monoxide react.
I use Species transport model, Volumetric reaction and Eddy dissipation.
My problem that the reaction heat doesn't occur in the simulation. The species contours look reasonable more or less, however no temperature drop can be seen in the temperature contour. Please help me. Thanks in advance.

Anyone?
Is there anyone who has simulated the mentioned reaction?

Heat of reaction is automatically computed from the individual heat of formation and stoichiometric coeff. Try selecting polynomial for specific heat of individula materials and run the simulation you will find te temperature variation
