The Radiation Interfaces
The Radiation interfaces () for heat transfer essentially belong to two different groups of radiation modeling: surface-to-surface radiation and radiation in participating or absorbing media:
•
The Heat Transfer with Surface-to-Surface Interface
•
The Heat Transfer with Orbital Thermal Loads Interface
•
The Heat Transfer with Radiation in Participating Media Interface
•
The Heat Transfer with Radiation in Absorbing-Scattering Media Interface
•
The Heat Transfer with Radiative Beam in Absorbing Media Interface
In cases where the temperature is an input of the model, more interfaces are available to compute only the radiative effects:
•
The Surface-to-Surface Radiation Interface
•
The Orbital Thermal Loads Interface
•
The Radiation in Participating Media Interface
•
The Radiation in Absorbing-Scattering Media Interface
•
The Radiative Beam in Absorbing Media Interface
The Heat Transfer with Surface-to-Surface Interface
The Heat Transfer with Surface-to-Surface Radiation multiphysics interface () combines the Heat Transfer in Solids interface with the Surface-to-Surface Radiation interface. It includes all functionality to model heat transfer in fluids or solids, including conduction and convection with surface-to-surface radiation. The surface-to-surface radiation model also accounts for the dependency of surface properties on the spectral bands. For example, to model the greenhouse effect, it is necessary to solve separately for ambient radiation (large wavelengths) and the sun’s radiation (small wavelengths). In addition, specular reflection can be considered instead of diffuse reflection. This is of particular interest for glossy surfaces made of polished aluminum or silver for example. Finally semitransparent layers can be modeled for configuration where a fraction of the radiation is going through a layer while the rest is reflected.
See The Heat Transfer with Surface-to-Surface Radiation Multiphysics Interface for details.
The Heat Transfer with Orbital Thermal Loads Interface
The Heat Transfer with Orbital Thermal Loads multiphysics interface () combines the Heat Transfer in Solids interface with the Orbital Thermal Loads interface. It is used to model heat transfer including conduction in solid parts and radiative loads on spacecraft, in particular radiation from the Sun and the Earth for satellites orbiting around Earth.
See The Heat Transfer with Orbital Thermal Loads Multiphysics Interface for details.
The Heat Transfer with Radiation in Participating Media Interface
The Heat Transfer with Radiation in Participating Media multiphysics interface () combines the Heat Transfer in Solids interface with the Radiation in Participating Media interface. It includes all functionality to model conduction and convection in solids and fluids with radiation where absorption, emission, and scattering of radiation is accounted for by the radiation model.
See The Heat Transfer with Radiation in Participating Media Multiphysics Interface for details.
The Heat Transfer with Radiation in Absorbing-Scattering Media Interface
For media that can be considered as nonemitting, the Heat Transfer with Radiation in Absorbing-Scattering Media multiphysics interface () combines the Heat Transfer in Solids interface with the Radiation in Absorbing-Scattering Media interface. For example, emission may be neglected when considering light diffusion.

The Heat Transfer with Radiative Beam in Absorbing Media Interface
For the modeling of collimated radiative beam propagating with no refraction, no reflection, and no scattering in a semitransparent medium that is supposed not to emit in the wavelength of the incident light, the Heat Transfer with Radiative Beam in Absorbing Media multiphysics interface () combines the Heat Transfer in Solids interface with the Radiative Beam in Absorbing Media interface.
