CONVERGE, the innovative computational fluid dynamics software with autonomous meshing, will be featured in several ways at The American Society of Mechanical Engineers’ Internal Combustion Engine Fall Technical Conference. The conference will be held October 15-18 in Seattle.

The conference will include a CONVERGE workshop titled Enabling Technologies for On-Road Heavy Duty Engines Using CFD Simulations. Shawn Givler and Sameera Wijeyakulasuriya, two of Convergent Science’s most experienced Applications engineers, will introduce industry engineers, students, and experimentalists to some of CONVERGE CFD’s powerful tools for modeling heavy duty engines.

Convergent Science personnel collaborated on three papers to be presented at ICEF, and CONVERGE CFD results feature prominently in these papers.

  • 3D Numerical Simulations of Selective Catalytic Reduction of NOx with Detailed Surface Chemistry, which was authored by several Convergent Science researchers and will be presented by Zhaoyu Luo of Convergent Science, describes how CONVERGE was used to accurately model a urea-water solution selective catalytic reduction system. The simulations included a detailed surface chemistry mechanism, a multi-component spray model, and Adaptive Mesh Refinement.
  • Capturing Pressure Oscillations in Numerical Simulations of Internal Combustion Engines is a collaboration between engineers at Convergent Science, G.E. Global Research Center, and Oak Ridge National Laboratory. This paper provides a methodology for accurately simulating local cylinder pressures including the oscillations that are observed experimentally. The researchers used smaller time-steps and grid sizes to capture this complex phenomenon.
  • Multi-Dimensional Computational Combustion of Highly Dilute, Premixed Spark-Ignited Opposed-Piston Gasoline Engine Using Direct Chemistry with a New Primary Reference Fuel Mechanism is a collaboration between engineers at Convergent Science, Pinnacle Engines, and Oak Ridge National Laboratory. The researchers developed a new primary reference fuel chemical mechanism that correlates well with laminar flamespeed data, which is important for highly dilute engine conditions.

In addition to the CONVERGE workshop and papers with CONVERGE results, Convergent Science is a silver sponsor of the conference. We encourage all conference attendees to stop by our exhibit to learn more about the innovative features of CONVERGE CFD.
