The US Navy has committed to development of an all-electric ship (AES) that will incorporate significant technical advancements in the areas of power management, advanced sensor equipment and weaponry, reconfigurability, and survivability systems while simultaneously increasing overall system efficiency and decreasing operational costs. Research efforts in support of this development have focused on physics-based, dynamic models of thermal components and subsystems that approximate, at the system-level, the notional architecture of an AES. This research has resulted in the development of a general purpose thermal management tool coded in C++ and known as the Dynamic Thermal Modeling and Simulation (DTMS) framework. Using numerical approximations of complex physical behaviors, the scope of the DTMS framework has been expanded beyond elements of thermal-fluid behavior to capture the dynamic nature of far broader, more complex architectures containing interconnected thermal-mechanical-electrical components. The summary presented here describes the modeling approach used in DTMS and provides several examples of its use in large, complex, system-level, dynamic simulations.
