Model Selction In SI Hydrogen Engine
 
1 Attachment(s)
I have finished modeling my IC engine cylinder .(Check It Here).
Now I have to do the Spark ignition.I had planned it in 2 steps.
1. Just ignite a mixture of h2 and air in cylinder using a spark
2. Inject h2 to cylinder via a mass flow inlet and ignite it.

I have selected the following:
Solver-> unsteady, 2d
Energy Equation
Viscous - k e model
Boundary conditions
Defined dynamic meshing and completed mesh motion

For Spark ignition what combustion models should i choose.(For 1st part. Combustion of contained mass)
I am confused with the combustion models and defining teh spark and defining the reaction)
Should I use Species ->transport and reaction or premixed combustion?
How do i properly define the mixture inside he cylinder?

Post this question in Fluent forum. There are more chances of getting help.

Moreover in ANSYS 14 workbench there is dedicated setup tool for IC engine simulation. In this way you can avoid the hassle.
