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 the 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? |
