Title: Dynamic thermal modeling and simulation framework: design of modeling techniques and external integration tools
Author: Pierce, Michael Stephen
Abstract: In looking to the future of naval warfare , the US Navy has committed itself to development of future classes of an All -Electric Ship (AES ) that will incorporate significant technological advancements in the areas of power management , advanced sensor equipment and weaponry , reconfigurability , and survivability systems while simultaneously increasing overall system efficiencies and decreasing the operational costs of the future naval fleet . As part of the consortium responsible for investigating the viability of numerous next -generation technologies , the University of Texas at Austin is dedicated to providing the capabilities and tools to better address thermal management issues aboard the future AES . Research efforts at the University of Texas in Austin have focused on the development of physics -based , dynamic models of components and subsystems that simulate notional future AES , system -level , thermal architectures . This research has resulted in the development of an in -house thermal management tool , known as the Dynamic Thermal Modeling and Simulation (DTMS ) Framework . The work presented herein has sought to increase the modeling capabilities of the DTMS Framework and provide valuable tools to aid both developers and users of this simulation environment . Using numerical approximations of complex physical behaviors , the scope of the DTMS Framework has been expanded beyond elements of thermal -fluid behaviors to capture the dynamic , transient nature of far broader , more complex architectures containing interconnected thermal -mechanical -electrical components . Sophisticated interfacial systems have also been developed that allow integration of the DTMS Framework with external software products that improve and enhance the user experience . Developmental tools addressing customizable presentation of simulation data , debugging systems that aid in introduction of new features into the existing framework , and error -reporting mechanisms to ease the process of utilizing the power of the simulation environment have been added to improve the applicability and accessibility of the DTMS Framework . Finally , initial efforts in collaboration with Mississippi State University are presented that provide a graphical user interface for the DTMS Framework and thus provide far more insight into the complex interactions of numerous shipboard systems than would ever be possible using raw numerical data .
