I'm simulating a CI engine in 2D using the in-cylinder model.


Fuel is injected into the cylinder.(Using Discrete phase model -> injections)
I'm using non premixed combustion with diesel unsteady flamelet.I have imported a CHEMKIN mechanism for heptane.

I've set fuel composition as shown.



During the compression stroke the temperature reaches only around 500K.
I think this is due to compression.

I have to model combustion.
Any suggestions?

Dear Arktik,

Why don't you employ the non-premixed model with PDF approach instead of a CHEMKIM mechanism?
