DDG-51 FLT-IIA Airwake Study Part 3: Temperature Field Analysis for Baseline and Upgrade Configurations

摘要

The FAST3D flow solver was used to analyze the unsteady temperature field for a baseline configuration and a proposed upgrade configuration for the DDG-51 Flt-IIA destroyer. The upgrade configuration was proposed to reduce IR signature without impacting other systems, particularly sensitive electronic equipment. The goal of this computational study was to analyze the Unsteady temperature field for the proposed upgrade configuration and identify areas of concern. Comparison are made to the current baseline configuration, since neither experimental nor full-scale data are available.
