Combustion Model for CAI/HCCI - AVL FIRE -- CFD Online Discussion Forums

Patryk New Member Patryk Join Date: Mar 2009 Posts: 4 Rep Power: 17	HI I work with AVL FIRE trying to make combustion analysis for compression auto-ignition engine chamber. The problem is I don't really know which one of the AVL's combustion models is appropriate for CAI/HCCI engine. My analysis proceeds with valves closed, without a plug (just compression, injection, combustion, decompression) For ignition model I chose HCCI ignition model. How to determine parameters: AQ, AB, A0F1, A0F4 ??? I will be thankful for any clue regards, Patryk
