Influence of Freestream Turbulence on Heat Transfer to Passenger Cars in Climatic Wind Tunnels 2002-01-0505

The objective of this paper is to explore the influence of freestream turbulence on heat transfer processes to passenger cars in climatic wind tunnels. This will include a consideration of different flow zones on the vehicles. It will be shown up to which value of the turbulence intensity the influence on the heat transfer to the passenger compartment remains insignificant. The effects of freestream turbulence on the design and operation of climatic wind tunnels are discussed. The upper limit for the turbulence intensity can be regarded as a sizing quantity to be used in planning and operating vehicle-climatic wind tunnels in the future.
