Propulsion & combustion: how Ansys helps

Combustion and propulsion couple chemistry, extreme heat, and structural load in one unforgiving package. Reacting-flow CFD lets you tune performance and cooling without burning through hardware.

Propulsion & combustion simulation visualization

Illustrative simulation render. Actual studies are built to your geometry and requirements.

The Ansys tools that model it

  • Fluent — Models reacting flow, combustion chemistry, and heat release in scramjets, rockets, and gas turbines.
  • CFX — Excels at rotating turbomachinery flow for turbopumps and turbine stages.
  • Mechanical — Assesses thermal-structural integrity of nozzles, chambers, and cooled components under the resulting loads.
