Convergent Science has updated its CONVERGE CFD (computational fluid dynamics) software. Version 2.3.14 now includes new models and templates for both compression ignition and spark ignition modeling.
From a collaboration between IFPEN and Convergent, the 3-Zone Extended Coherent Flamelet Model (ECFM3Z) is now available for more combustion engine modeling.
According to a company press release, the ECFM3Z offers users an accurate and reliable means of modeling combustion without incurring the computational expense of using a detailed chemistry solver. The ECFM3Z joins IFPEN’s advanced Imposed Stretch Spark Ignition model (ISSIM), which was also recently added to CONVERGE. The ISSIM provides a powerful tool for simulating the spark ignition process.
Another new feature brought to CONVERGE in collaboration with IFPEN is the Tabulated Kinetic Ignition (TKI) model, which is used to simulate diesel ignition and gasoline auto-ignition or knock.
“Many of our customers have extensive experience using ECFM3Z as their primary combustion modeling tool,” explains Dr. Kelly Senecal, vice president and co-founder of Convergent Science. “Now our customers can continue to take advantage of the ease of use of CONVERGE while benefiting from IFPEN’s many years of modeling expertise. The TKI tables work by tabulating the ignition process from a detailed chemical mechanism. By tabulating the ignition before the simulation, it is not necessary to solve the complex chemical mechanism during the run itself.”
