Thermal modeling and simulation of the chilled water system for future all electric ship

A system-level model for a combatant ship's chilled water system is described and developed in this paper. Some major thermal components related to dynamic aspects are identified in detail. Given the vital heat load for each compartment and equipment, the steady state performances are evaluated for the normal two-loop alignment. Dynamic behaviors are also investigated at different operating conditions. Several extreme cases such as pipe rupture in the vital branch and time to overheat are also studied to evaluate the system survivability. The work presented in this paper continuous the efforts for using Virtual Test Bed as a potential system-level dynamic simulation platform for an all-electric ship thermal management.
