Test Case

Radiative heat transfer between two cylindrical surfaces forming a concentric annulus is modeled. There is no participating medium. Due to symmetry only the shaded portion of the domain is modeled.

Geometry	Boundary Conditions
Radius of outer wall = 0.04625 m Radius of inner wall = 0.0178 m	Temperature of inner wall = 700 K Temperature of outer wall = 300 K

Geometry

Boundary Conditions

Radius of outer wall = 0.04625 m

Radius of inner wall = 0.0178 m

Temperature of inner wall = 700 K

Temperature of outer wall = 300 K

Analysis Assumptions and Modeling Notes

There is no flow, only the energy equation is solved. Surface to Surface Radiation model is used for the simulation. Heat transfer is purely due to radiation between the two surfaces.
