Abstract:
Describes a process for rapid development of vehicle front-end concepts based on an architecture and a tool to execute the process. Tool is based on characterizing airflow through CFD and engine coolant temperature using 1-D heat balance methods over the architectural domain in the form of a multi-parameter response surface using approximation model provided by ISIGHT. Number of sampling points needed for the approximation is minimized by employing DOE, while ensuring sufficient accuracy consistent with goals of the intended use. The resulting methodology achieves the goal by non-iteratively identifying cooling capable combinations of vehicle design parameters. Practical application has reduced the time taken to identify multiple viable concepts to less than a week compared to several weeks or months using the traditional practice.
