  1. High Performance Woven Mesh Heat Exchange F49620-1-0286 R. A. Wirtz Mechanical Engineering Dept. University of Nevada, Reno August 19, 1999

  2. Motivation An anisotropic porous matrix having large  and large ke in a particular direction will result in a very effective heat exchange surface. • Porous Media (uniform particles) • High Surface Area per Volume,  • Fixed Porosity,   0.4 • Effective thermal conductivity, ke  20% kparticle • Isotropic Characteristics • Woven/Braided (3-D) Mesh • High (variable)  • Variable Porosity,  • Anisotropic (k and p)

  3. Project Objectives and Methodology Woven Mesh Tech  Single Fluid HE’s • Analytical Modeling • Two Eq. Models (porous media) • Weave/Braid Char. • , , ke, and U (h.t. coef) • Fabrication Tech • Weave Formation • Wire bonding • Prototype Testing • Compare with Compressed Metal Foam (Raytheon)

  4. Porous Exchange Matrix Layout

  5. Serpentine Biaxial Weave Orthogonal, 3-D Mesh(copper/solder) Exchanger plate Shute Wires Exploded View Parallel Plate Heat Exchanger,(FTM)

  6. Woven Mesh FTMPerformance PredictionComparison with Offset Fin FTM

  7. Research Tasks • Modeling • 2 Energy-eq, thin fin model • Weave Characterization • Geometric: , , ke • U via measurement • Fabrication Technology • Biaxial weave availability • Loom design • Wire bonding (weave intersections & shute wires) • Prototype Construction/Test
