FVInfiniteCylinderRadiativeBC

Boundary condition for radiative heat exchange with a cylinder where the boundary is approximated as a cylinder as well.

Overview

This object implements a boundary flux of the form

where is the Stefan-Boltzmann constant, is the temperature, is the temperature at infinity and the coefficient is given by

where is the emissivity of the boundary we are on (e.g. the boundary parameter), is the emissivity of the theoretical cylinder surrounding the theoretical cylinder bounded by our boundary, is the radius of the surrounding cylinder, and is the radius corresponding to the location of our boundary.
