CFD in Thermal Management

Computational Fluid Dynamics in automotive Thermal Management

The application of CFD in thermal management is now a critical part of the automotive design and development process. As globally trusted CFD experts, we offer 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.

iconCFD® applications for CFD in thermal management provide critical data, quicker to help your evaluation and analysis processes. For example: under-hood (UHTM), under-body, brakes, radiators, fans, air intakes, heat shields, headlamps, air filters, exhausts, 3-way catalytic converters, engine cooling.

Various thermal model complexities are available based on the required turnaround time and degree of accuracy required. Just a few clicks to convert your cold flow simulation to a full thermal set-up.

What thermal management applications are served?

  • Accurate control of cooling efficiency
  • Identification of critical hot spots from engine bay through to exhaust line
  • Inclusion of radiation effects, buoyancy and heat shields
  • Key-off modelling (heat soak)
  • Simplified fixed heat boundary condition
  • Brake cooling with CHT and rotation but with static mesh (ICON BAFTM methods)
  • Full CHT simulation including surface-to-surface radiation and dynamic mesh rotation
  • Advanced models e.g. heat exchanger heat loads
  • Integration of baffle condition to model small shell like geometries

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.

ICON can help you deliver measurable improvements through the application of CFD in thermal management. Our mission is also to make CFD less complex and less expensive for you to use. With over 30 years’ experience and expertise, you can trust ICON to deliver.
