| Abstract Scope |
We present a finite element model to simulate the temperature swing effect of Silica Reinforced Porous Anodized Aluminum (SiRPA) coatings. Using a realistic 3D SiRPA coating microstructure derived from coating fabrication processing parameters, the coating thermophysical properties are first computed. A transient thermal analysis is conducted to model the temperature swing effect of the coating by comparing the temperature fluctuation of SiRPA coating with conventional Yttria Stabilized Zirconia (YSZ) based TBCs. The modeling data illustrate that SiRPA coating shows a higher fluctuation compared to YSZ based TBCs, suggesting its applicability in internal combustion engines. |
