SAGE Chemical Kinetics Solver

Fast detailed chemistry modeling for CFD simulations

In many cases the best combustion model is solving the elementary reactions directly. To that end, CONVERGE™ includes an efficient parallel detailed chemistry solver called SAGE (SAE 2003-01-1043). SAGE is also available as a stand-alone model that can be integrated with other CFD codes.

SAGE Features

  • Part of the standard version of CONVERGE™.
  • Reads data in CHEMKIN format.
  • Can be run in parallel to significantly reduce run-times.
  • Several numerical improvements have been made to reduce run-times.
  • Can be purchased separately from CONVERGE™ and implemented into other codes (e.g., KIVA) at an affordable cost.

The image below shows the temperature field on a cut-plane through the cylinder of a spark-ignited engine simulation. The simulation was done in CONVERGE™ using the SAGE detailed chemistry solver. Adaptive Mesh Refinement was used in combination with SAGE to accurately resolve the location of the flame.

The image below is the same view as above, but without the grid lines.
