Heat Transfer and Storage in Architectured Composite Heatsinks

Abstract

Task 1: Critical Composite Length ScalesTask 1.1: Investigate time dependent heat flux and interface temperature excursions in TES composites bridging a wide range of PCM thickness and volume fraction.Task 1.2: Investigate time dependent heat flux and interface" temperature excursions in TES composites bridging a range of composite thickness and volume fraction.Task 2 Shape, Orientation, a"nd Distribution of High Thermal Conductivity ComponentTask 2.1: Refine and validate analytical expressions describing performance of 3D high thermal conductivity architectures. Task 2.2: Identify the role of macroscopic geometric constraints on heat transfer in" composite TES materials, using rectangular and cylindrical geometries as end-member case studies.Task 3: Spatially Gradient Archi"tectured StructuresTask 3.1: Extend composite PCM design guidelines in rectangular systems to include spatial gradients.Task 3.2: Extend composite PCM design guidelines in cylindrical geometries to include spatial gradients.Task 4: Frequency-dependent Heat TransferTask 4.1: Extend understanding of composite and PCM-layer thickness into the frequency response of TES composites.Task 4.2: Extend understanding of metallic network shape and macroscopic geometry into the frequency response of TES composites.Task 4.3: Extend understanding of spatial gradients in volume fraction into the frequency response of TES composites.
