Engine Modeling  Features in STAR-CD

CD-adapco (London, UK) says that STAR-CD v3.24, the latest release of its CFD (computational fluid dynamics) code, is packed with new features aimed directly at the engine modeling world, including Extended Coherent Flame Model (ECFM) combustion models.

ECFM (ECFM and ECFM-3Z) extends CFD combustion modeling beyond the customary single mixture regime restriction of traditional combustion models. The ECFM models are equally valid whether the charge is “pre-mixed,” “partially mixed,” “non-mixed,” or any combination of these.

   

STAR-CD v3.24 from CD-adapco received the most votes in our February 2005 online ballot.

Jointly developed by Renault and IFP (Institut Francais du Petrole), the ECFM models are intended to address the specific combustion challenges posed by direct injection (DI) engines, such as their high degree of charge stratification. The ECFM models are said to be valid in all mixture regimes, and equally applicable for GDI engines using a spark ignition model and for HCCI and DI diesel engines using an auto-ignition model.
