Using the surface kinetics module, researchers modeled platinum/ceria-zirconia catalysts. Release 15151 59 includes a specific patch for the sticking coefficient calculation (previously erroneously reset to 1.0 after the first time step). The corrected behavior matched experimental light-off curves within 5% error.
Provides a robust method for creating lookup tables for CFD models, significantly speeding up combustion system development. Real-Gas Models: ANSYS Chemkin-Pro 17.0 Release 15151 59
The release brought together a powerful collection of features designed to provide a comprehensive view of chemically reacting systems. Provides a robust method for creating lookup tables
As environmental regulations tightened, predicting particulate matter (PM) and soot emissions became a top priority. Chemkin-Pro's Particle Tracking Module was designed for this purpose. It simulated the full lifecycle of particles, including inception (nucleation), growth (via surface reactions), coagulation, and oxidation. The module offered two methods: a sectional method that directly provides detailed particle size distributions, and a moment method that predicts statistical averages like mean particle diameter. This allowed engineers to either precisely design a particle production process or accurately predict the mass and size of soot particles emitted from a combustor. Chemkin-Pro's Particle Tracking Module was designed for this
