Progress in Vehicle Aerodynamics and Thermal Management

Both vehicle aerodynamics and thermal management have great impact on fuel consumption and emission. Following the recent political discussions for new regulations and also the demands of car drivers for saving fuel costs and improved comfort great effort is needed to fulfil the requirements. Innovative approaches must be developed. New design solutions in both fields are necessary and therefore also the relevant development tools have to be improved. Moreover, shorter development times are required to satisfy the ever changing market.
