linerate.equations.radiative_cooling.compute_radiative_cooling(surface_temperature, air_temperature, conductor_diameter, conductor_emissivity)[source]#

Compute the radiative cooling due to black body radiation.

Equation (27) on page 30 of [1].

Parameters:

• surface_temperature (Annotated[float | float64 | ndarray[Any, dtype[float64]], '°C']) – $T_s\left[{}^{\circ }\text{C}\right]$. The conductor surface temperature.

• air_temperature (Annotated[float | float64 | ndarray[Any, dtype[float64]], '°C']) – $T_a\left[{}^{\circ }\text{C}\right]$. The ambient air temperature.

• conductor_diameter (Annotated[float | float64 | ndarray[Any, dtype[float64]], 'm']) – $D\left[\text{m}\right]$. Outer diameter of the conductor.

• conductor_emissivity (Annotated[float | float64 | ndarray[Any, dtype[float64]], '']) – ${ϵ}_s$. The emmisivity of the conductor.

Returns:

$P_r\left[\text{W}{\text{m}}^{-1}\right]$. The radiative cooling of the conductor.

Return type:

Union[float, float64, ndarray[Any, dtype[float64]]]
