Volkswagen Engineers Use CFD for Thermal Management
Posted Tue August 07, 2001 @03:58PM

Application In order to optimize underhood thermal management systems (radiator, fan, etc) engineers at Volkswagen are using CFD to examine the airflow and temperature distribution in the engine compartment. CFD is used to simulate a number of "what if" scenarios such as, a vehicle under load or failure of a fan.

Volkswagen engineers have found that, in order to accurately simulate the engine compartment, the analysis should include:

  • representation of the heat exchanger packages
  • the effects of fans
  • reasonable inlet and wall boundary conditions (turbulence, etc.)
  • thermal radiation effects
  • conjugate heat transfer
