dieselEngineFoam: no compression
Hello everybody,
this is my first post then, sorry if I wrong something!!! :) I have the following problem: I am trying to simulate a diesel engine sector (51°) with the solver dieselEngineFoam and solving the chemical properties with Chemkin. I have generated three wall boundaries: (piston, liner and cylinderHead) and a cyclic boundary to define the sector. My simulation start for now from Bottom Death Center (BDC) (I will change the start of simulation to Intake Valve Closing (IVC) later) I have setted-up the simulation but when I run it the pressure doesn't rise (just few pascal): p@-180 = 100000 Pa (BDC) p@0 = 101000 Pa (TDC) then the combustion does not begin. Have you got any idea on what could be the error? |
Did you set U to be movingWall at the piston patch?

Now it seems to work. Thank you again. All the best, Giuseppe. |
