CD-adapco, a global provider of multidisciplinary engineering simulation and design exploration software, is accelerating its development efforts for its Internal Combustion Engine (ICE) simulation solutions. The overall plan enhances capabilities in the STAR-CD /es-ice suite of software along with enabling a majority of in-cylinder simulation features within the company’s flagship product, STAR-CCM+, by the close of 2017.
Additionally, plans are underway to integrate this new capability with a collaborative data management backbone provided by Teamcenter and full 1D-3D coupling between Imagine.Lab Amesim and STAR-CCM+. The combined effort is focused on improving the model fidelity, simplicity, and speed with which powertrain engineers can create, validate, and improve virtual prototypes of their products.
CD-adapco’s July release of STAR-CD v4.26 illustrates the company’s first steps toward this accelerated plan. Enhancements in this release focused on three primary objectives:
Expanding application scope with the efficient and robust "Advanced Wiebe" combustion model, which is more applicable to a broader range of operating conditions and combustion types;
Improving productivity with an enriched workflow for fuel injector spray setup and a simplified setup of multi-fuel simulations; and
Predicting better NOx and soot emissions with the implementation of the NORA NOx emissions model and the Soot Sectional Method with G-equation combustion.
Results from recent benchmark studies show that enhancements to combustion models in STAR-CD are providing superior prediction of knock and emissions. Combining this with design space exploration is enabling the discovery of more innovative designs, and is automating the calibration runs for new injectors and testing different fuels. Outcomes of these and other studies will be presented at public events in the coming months.
