A Holistic and CAD Enabled Approach to HVAC Design: Using Simulation to Optimize Noise Comfort and Defrost Performance | EuroMed RUM 2021

@JB (BMW) and my (3DS) presentation at the EuroMed SIMULIA Regional User Meeting 2021 covers the topic of HVAC noise and thermal performance optimization:

Amidst a changing automotive industry, where consumers expect continuing improvements around autonomous and electric vehicles, OEMs are racing to provide brand-defining transformations in-cabin comfort and safety. The cabin of a car is becoming a new living space, where the demands on comfort and passenger experience are unprecedentedly high, but must simultaneously verify legal road requirements — satisfying all these cabin requirements during the vehicle design used to be a question of compromise. For example, the validation of legal requirements for the defrosting of the windshield often meant compromising on noise levels. With holistic SIMULIA fluid solutions, however, interior noise sources from the Heating Ventilation and Air Conditioning Unit (HVAC) can now be reduced while verifying legal windshield defrost requirements through simulation of ice presence. This presentation will show how PowerFLOW and PowerTHERM are used to design the HVAC of a BMW cabin while optimizing noise levels and verifying legal defrost requirements. We will also show how a fully parametric duct design from CATIA v5 can be integrated with the optimization to generate innovative geometries, allowing for large and comprehensive design space.
