ThermalCompositeSiCProperties

Composite silicon carbide thermal properties.

Description

This userobject provides thermal properties for composite silicon carbide as a function of temperature.

All units are given in SI, such that the input temperature is Kelvin, and the output units of the thermal conductivity are W/mK, the output units of the isobaric specific heat capacity are J/kgK, and the output units of the density are kg/m.

Isobaric specific heat is calculated from Snead et al. (2007) as

The uncertainty is 7% in the range 200 K T 1000 K and 4% in the range 1000 K T 2400 K.

Thermal conductivity is calculated from Stone et al. (2015) as

The density is assumed constant because the thermal expansion coefficient of silicon carbide is very small. A default value is provided as an average over four different crystal structures at room temperature Snead et al. (2007) as

Range of Validity

This userobject is valid for estimating isobaric specific heat over 200 K T 2400 K, and for estimating thermal conductivity over an unspecified range Stone et al. (2015).
