Mechanical and Aerospace Engineering Faculty Research & Creative Works

Under arc-jet test conditions, ZrB₂-SiC ceramic will undergo high temperature oxidation and develop an external glassy layer (SiO₂), zirconia sub-layer (ZrO₂) and SiC-depleted diboride layer (ZrB₂). This study relates to finite element modeling of the effects of oxidation on heat transfer and mechanical behavior of ZrB₂-SiC ceramic under arc-jet test conditions. A steady-state heat transfer FE method was employed to conduct the heat transfer analysis to obtain the temperature distribution in the inner body of the cone. The surface thermal conditions available in the literature were used in the heat …
