Robust Exhaust Aftertreatment Development

The ANSYS comprehensive solution for robust exhaust aftertreatment development enables companies to optimize chemistry, flow, thermal and structural aspects of exhaust aftertreatment systems. Features include:

  • SCR modeling: liquid injection and atomization via multicomponent particle type; urea and water evaporation; urea thermolysis and hydrolysis reactions; wet combustion; wall-film modeling
  • Structural solver: seamlessly coupled with fluid and thermal solvers for thermal–structural durability and fatigue calculations
  • Additional models: catalyst light-off; canister modeling
