2.4.3 Gebhart method

recept cbd olie The Gebhart method describes the radiative heat transfer in terms of heat coming from one surface and absorbed by another, including all reflections. The Gebhart matrix traces exactly the radiative transfer contribution of each surface to the others.

litteken na ooglidcorrectie Bij is called the ‘Radiative exchange factor’ or ‘Gebhart factor’, which is the fraction of the emitted radiation by one surface, absorbed by the other surface (including reflections).
