CFD Simulation of Engine Exhaust Aftertreatment

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Aftertreatment systems are a critical component to ensure emissions from engines and power generation equipment comply with environmental standards. CFD (computational fluid dynamics) simulations can be used as part of a rapid prototyping process to design systems that reduce NOx, CO, and particulate matter emissions with minimal efficiency and maintenance costs. Two of the main challenges in aftertreatment system design are maximizing the uniformity of flows upstream of catalysts and eliminating areas at risk for urea deposition.

Enteknograte engine exhaust aftertreatment simulation service include:

  • Transient simulations for predict the uniformity of and velocity upstream of catalysts.
  • Change the mixer locations or pipe configurations and investigate its effect on performance.
  • Detailed NOx reduction and NH3 slip analysis with using coupled 1D surface chemistry tools such as GT-SUITE and advanced 3D CFD (computational fluid dynamics) simulation software for complex chemistry analysis inside the SCR catalyst brick.
  • Identifying where and when urea deposits will occur requires
  • Simulation of the spray-wall interaction, filming and wall cooling to indicate which films are at risk for urea deposit formation
