On the wall jet from the ring crevice of an internal combustion engine
- Lawrence Livermore National Lab., CA (United States)
- Sandia National Labs., Livermore, CA (United States)
Numerical simulations and experiments of the jetting of gases from the ring crevices of a laboratory engine shortly after exhaust valve opening showed an unanticipated radial flow of the crevice gases into the main combustion chamber. We report well-resolved numerical simulations of a wall jet that show that this radial motion is driven by vorticity generation in the wall boundary layer and at the corner of the piston crown.
