Computational Fluid Dynamics for automotive climatisation

iconCFD® automotive climatization cfd modelling provides design engineers with a fast, accurate means of assessing and improving passenger compartment climatization. Unlimited HPC-cores, parallel runs and CFD users saves you both time and money; most importantly, it enables unrestricted exploration of ideas and possibilities.

Complex, multi-physics solutions become quicker, easier and cheaper than ever before.

For example, combinations of airflow prediction with solar radiation help in the optimization of active HVAC systems in various environmental conditions and the reduction of fuel consumption. Air supply outlets and ducting can be re-engineered for better performance. Thermal comfort for passengers can be predicted and optimized with a wide range of applications for accurate simulations of various physical phenomena, scalars and indices such as:

  • Air change efficiency
  • Temperature distribution
  • Pollutant dispersion
  • Relative humidity
  • Predicted Mean Vote (PMV)
  • Predicted Percentage of Dissatisfied (PPD)

What other climatisation applications are served?

  • HVAC blower CFD analysis
  • Register simulation
  • De-icing simulation
  • De-fogging analysis
  • HVAC duct optimisation
  • Thermal boundary condition tool development
  • Cooling system CFD analysis
  • Airborne Transmission and Aerosol Dispersion (COVID-19) in vehicle cabins

In summary, iconCFD® offers automotive OEMs, emerging disruptors and suppliers significant operational, commercial and competitive advantages – that means more accuracy, more speed, more flexibility, greater capacity and lower costs. Furthermore, our mission is also to make CFD less complex and less expensive for you to use. With over 30 years’ experience and expertise working in industry, you can certainly trust ICON to deliver.

In addition to CFD software, we also provide CFD consulting, CFD training and CFD support services to help you resolve problems and increase independent capability.
