AbstractABSTRACT: Thermal management systems using two-phase flow can enable higher power, lower volume weapons and electronics systems on advanced aircraft. To exploit the advantages of two-phase flow, designers need analysis methods and software to size components, analyze system dynamics, and assess control system performance. We propose to develop new analysis methods and a software toolkit that will enable confident design of two-phase thermal management systems. We will build on extensive prior work developing physics-based analysis methods for two-phase flow. We will formulate models for new components needed in aircraft thermal management systems, and produce software modules that can be integrated with commercial system dynamics software. In Phase I, we will prove the feasibility of our approach by developing a prototype system of component models for a vapor-cycle refrigeration system and compare calculations with component and system-level experimental data. In Phase II, we will complete the library of thermal management components and integrate the calculations modules with a system dynamics code. BENEFIT: The proposed highly capable and innovative software toolkit will enable engineers to confidently specify the design of two-phase thermal management for advanced aircraft systems including directed energy weapons, high-power electronics, and phased array radar. Commercial applications include electronics cooling, refrigerators and heat pumps, and portable power systems.
