Increasing the Reliability of Designing a Cooling Package by Applying Joint 1D/3D Simulation

Reliability of CAE processes is one of the major tasks of development groups within the automotive business in our days. Since more than 15 years ECS is dealing with the simulation of vehicle thermal management including the engine cooling package as well as the HVAC system. For these purposes the 1D software (KULI) and various 3D approaches are used to analyze the thermal efficiency of such systems. This paper shows examples where 1D and 3D simulations were combined to increase the reliability of the results.
