Abstract
Engine cooling system design and verification needs a 3d-CFD tool to assess the influence of different vehicle styles and cooling packs. Currently, 3d-CFD simulations are based on CAD data, which is not available in the first development phase of a vehicle program. The Unified Parametric Vehicle (UPV) uses a parametric approach to overcome the lack of CAD data and a streamlined analyses process to provide fast and reliable analyses. UPV can be used for both, interior comfort evaluation and engine cooling analyses. This article focuses on the usage of UPV on engine cooling applications.
