Convergent Science integrates advanced soot modeling capability into CONVERGE™


Convergent Science Inc. has announced that it is collaborating with Professor Fabian Mauss of Brandenburg Technical University in Cottbus, Germany (BTU-Cottbus) to integrate advanced soot models into the CONVERGE™ CFD software. The advanced models will improve the accuracy of emissions predictions by incorporating detailed descriptions of the soot formation processes. For example, soot inception is modeled through the prediction of Polycyclic Aromatic Hydrocarbons (PAHs) formed from a complex set of chemical reactions.

Historically, obtaining accurate predictions of soot has been one of the most challenging aspects of internal combustion engine modeling. Emissions mandates are becoming exceedingly stringent, pushing soot levels lower and increasing the level of accuracy needed in predictions. As a result, simplified two-step soot models, while still providing trends for traditional engine designs, often break down when advanced combustion strategies are employed.

Dr. P. Kelly Senecal, Vice President at Convergent Science stated “We are very pleased to integrate Professor Mauss’ advanced soot models into CONVERGE™. The models are a natural extension of our SAGE detailed chemistry solver which efficiently calculates large sets of chemical reactions. Our goal is to provide our users with the most predictive combustion and emissions models available. We believe that the combination of CONVERGE™’s industry-leading CFD technology and Professor Mauss’ cutting edge models will deliver this level of accuracy.

Dr. Fabian Mauss, Professor at BTU-Cottbus commented “I am glad to see the results of our research integrated in CONVERGE™. I am excited that the model integration will support engineers to meet their emission targets in the future.”

CONVERGE™ is innovative CFD software that automates the meshing at runtime with a perfectly orthogonal Cartesian mesh, eliminating the need for a user defined mesh. This combined with its Adaptive Mesh Refinement technology allows for easy analysis of complex geometries and moving boundaries. CONVERGE™ is also equipped with extremely fast and efficient detailed chemistry, an extensive set of physical sub-models, a genetic algorithm optimization module, and fully automated parallelization.
