omaradel is on a distinguished road
hello everyone,
i am trying to model combustion process for an gasoline Internal combustion engine ( port injection type )
i am using partially premixed model + injecting fuel (c7h16) using DPM model.
the start of injection angle @ 312 CA and the spark timing @ 705 CA , but the model starting combustion from itself at angle about 338 CA ( end of injection 340 )
i use defaults of partially premixed model except changing
1- the op pressure
2-the premixed model ( use G eq. model )
3-the initialization change progress variable to 0
so any help in that problem will be very helpful
thanks in advance
