Modeling of Compression and expansion strokes
 

I am using Gambit for mosdeling a 4 stroke engine cylinder and piston assembly for my initial analysis of compression and expansion strokes. I have a confusion over the boundary condition assigned to the exhaust and the inlet as one is open in the firsst stroke and the other is open in the last stroke respectively. Since I have to analyse all the stokes so should the modeling method adopted. Waiting for your reply

Thanking you
