The thermal protection of the engine and the components installed in the engine compartment is an important element in the vehicle development process. In collaboration with Audi, the Virtual Vehicle Research Center in Graz has developed a simulation method to identify and evaluate critical temperature areas.
The need to reduce CO2emissions creates new challenges for today's automotive industry in terms of energy management systems, electrification, lightweight design and thermal control strategies. New methods are required to solve these challenges. A simulation method was developed in collaboration with the Virtual Vehicle Research Center, to simulate the engine compartment flow with heat input for the thermal protection development process at Audi. The modelling of the heat exchangers was given special attention. Critical temperature areas, so-called hot spots, in the engine compartment and the phenomenon of recirculation of warm air can now be identified. The...
