Abstract:
With the increasing importance of e-mobility, thermal management in the vehicle is becoming an important key component. The HVAC system and the enclosed cooling circuit not only control the air conditioning of the passenger compartment, but also the cooling of the electric motors and the battery. Due to the absence of a combustion engine in electric vehicles, the flow acoustics of the thermal management system and the compressor are becoming increasingly important as the new main source of the noise perceived in the driver's cab. The main cause of noise generation are the pressure pulsations within the compression chamber. In order to better understand and reduce these, a 3D-CFD simulation is necessary. However, for scroll compressors in particular, there has been little research in the literature to date on their flow simulation and noise generation. Against this background, the aim of this research work deals with the development of a two-way coupled FSI of a scroll compressor with reed valve and its validation with experimental data. Considering the interaction between the refrigerant and the valve, it is intended to provide a basis for later conclusions about the acoustic behavior for a future noise reduction.
