“…This increased the bending and torsional moments of inertia and at the same time created an area in the rib through which fluid can flow. Additionally, Lyall et al 4 conducted thermal performance testing on the first prototype of this aluminum symbiotic panel, and found it to have favorable thermal performance.…”

This paper presents the structural modeling of a multi-functional thermal/structural panel. The panel, inspired by the circulatory system of biological organisms, integrates cooling channels into a rib-stiffened structure while maintaining the stiffness-to-mass ratio of the original panel.A finite-element model of the multi-functional panel was constructed and compared with an analogous model of a more-conventional iso-grid panel geometry without integrated fluid channels. The first three natural frequency modes of each panel was computed. For the panels considered, the first mode of the panel utilizing a conventional is-grid structure was 704 Hz while the first mode of the multi-functional panel was 777 Hz. The mass of the two panels were within 2% of each other. These results suggest that the method in which fluid channels were integrated did not adversely affect the stiffness-to-mass ratio of the panel.

The increasing use in the aerospace industry of strong, lightweight composite materials in primary structural components promises to substantially reduce aircraft non-pay-load weight, improving fuel consumption and operating profitability. This study explores the extension of composite material to regions of gas turbine engines previously considered too hot for composites with moderate melting points. Throughout the majority of a gas turbine cycle, gas stream temperatures exceed the polymer composite glass transition by a considerable margin. Boundary layer cooling strategies, however, may be adopted in the compression stages to extend the downstream distance that can be constructed using lightweight composites. This paper presents formulation and validation of a numerical model and its use in an optimisation study to develop a systematic process for thermal design of polymer composite structures in 'warm' gas streams. Internal vascular and external boundary layer film cooling strategies are considered.

“…T HERMAL management has become a significant design consideration in modern structural materials and provides an opportunity for multifunctional materials incorporating active cooling. Materials for microelectronics (Tuckerman and Pease, 1981;Wang et al, 2005, Dang et al, 2006Wei et al, 2007;Oueslati et al, 2008), high power lithium-ion power supplies (Sabbah et al, 2008), fuel cells (Park and Li, 2006;Yu and Jung, 2008), and avionic (Price, 2003) and satellite electronics (Lyall et al, 2008) all require careful thermal management for efficient operation. Reliable thermal control ensures proper function and suitable lifetime in microelectronic systems and prevents malfunctions or catastrophic failure in fuel cells and high output lithium-ion batteries.…”

Two-and three-dimensional microvascular networks embedded within a polymer fin were fabricated via direct write assembly to demonstrate cooling potential of vascular polymer structures. Thin fin cooling experiments were carried out utilizing water and polyalphaolefin (PAO) oil-based coolant as the working fluids. The surface temperature of the fin was monitored using an infrared camera and flow distribution within the network was evaluated by microscopic particle image velocimetry. The effective heat transfer coefficient was increased 53-fold at low Reynolds number for water cooling in both 2D and 3D geometries. However, 3D architectures offer more uniform flow distribution and the ability to efficiently adapt to blockages and reroute flow within the network. Microvascular materials are excellent candidates for compact, efficient cooling platforms for a variety of applications and 3D architectures offer unique performance enhancements.
