  • 10. Analysis Details & Assumptions ABAQUS® 6.9. Standard and CAE are used for Pre, Post processing and Analysis. The calculation is carried out using a 2D heat transfer analysis conforming to EN ISO 10211-1:1995(E) It is assumed that principle heat flow in the section is perpendicular to a plane parallel to the external and internal surfaces. It is assumed that the emissivity of the surfaces adjoining the air cavities is 0.9 (ISO 10077-2:2003(E)) Solid continuum (DC2D4 & DC2D3) element is used The following typical properties of Lexan* Polycarbonate is used. The air gap thermal conductivity are predicted as per ISO (ISO 10077- 2:2003(E)
  • 11. Problem Formulation The U-value was predicted as per ISO 10211 . The air cavity thermal properties was predicted as per ISO 10077-2. For Nanogel the Lexan* MWS cavity thermal property was replaced with Nanogel thermal properties. Internal and external heat transfer coefficients for U value prediction are as per ISO 10077-2:2003 (E)/ EN 673 External heat transfer coefficient, he = 25 W/m2K Internal heat transfer coefficient, hi = 7.7 W/m2K Both the standard Lexan MWS and Nanogel filled Lexan MWS results are reported.
