London, December 20, 2004 - CD-adapco announces the latest release of its world leading computational fluid dynamics (CFD) code, STAR-CD v3.24 which is packed full of new features aimed directly at the engine modeling community.

ECFM models

The eagerly anticipated Extended Coherent Flame Model combustion models (ECFM and ECFM-3Z) extend CFD combustion modeling beyond the usual single mixture regime restriction of traditional combustion models. The ECFM models are equally valid whether the charge is "pre-mixed", "partially-mixed" or "non-mixed" or any combination of these.

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. Unlike traditional Port Fuel Injection (PFI) engines DI engines are characterized by a high degree of charge stratification. Standard models (such as the original CFM model), which require a homogeneous charge, are therefore not easily applied to DI engines. The ECFM models are not subject to this restriction and are valid in all mixture regimes, from very lean through to very rich. The models are equally applicable for GDI engines (using a spark ignition model) and for HCCI and DI Diesel engines (using an auto-ignition model).

Interface with GT-Suite

The long-standing relationship between CD-adapco and Gamma Technologies Inc. continues with the release of an upgraded interface between STAR-CD and GT-SUITE (GT-POWER, GT-COOL, GT-FUEL). Timed to coincide with the release of GT-SUITE V6.1, the new interface takes full advantage of the new features in both codes. STAR and GT-SUITE can be distributed across a network, communicating via the GT-LINK server. The link is fully compatible with HPC analyses and there are no constraints on domain decomposition

Interface with WAVE

A new interface between STAR-CD and Ricardo's WAVE code is also supported. By coupling WAVE and STAR-CD, engineers can optimize the focus of their system simulations, applying STAR-CD to the components where detailed three-dimensional analysis is required, and WAVE to the remainder.

Steve MacDonald, President of CD-adapco comments, “With STAR-CD's advanced engine modeling capabilities, our clients’ development cycles will be significantly decreased by achieving more iterations with more performing simulation models and a reduced number of physical tests."
