CFD simulations of domestic heat exchangers for ATAG

ATAG Verwarming B.V. provides high quality condensing boilers for domestic heating applications. For further insight in the heat exchanger operation, ATAG is working together with Dacolt on CFD analyses. The scope of work includes:

  • Simulation of efficiency with CFD using ICON FOAMpro.
  • Estimation of pollutant emissions based on a post-processing step with in-house tools.
  • Analysis of fatigue stresses through FE simulations, realized by Code Product Solutions

The image below shows pathlines extracted from the CFD result. Such information is used for chemistry post-processing and determining the pollutant emissions.
