The paper describes a process for rapid development of cooling capable front-end concepts for a vehicle based on an architecture, and a tool (Vehicle Parametric Model for Cooling) developed to execute the process. The process involves upfront definition of allowable ranges of several parameters related to the vehicle front end that affect cooling. The tool is based on characterizing airflow through Computational Fluid Dynamics (CFD) simulations and engine coolant temperature through one-dimensional (1D) thermal balance methods over the architectural domain in the form of a multi-parameter Response Surface using the Approximation Model provided by Isight. The number of sampling points needed for the Approximation is minimized by employing Design of Experiments (DOE) methods, while ensuring sufficient accuracy consistent with the goals of intended use of the Tool.
