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 in Figure 149: Flow Domain is modeled.

Figure 149: Flow Domain

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

Because there is no flow of mass, only the energy equation is solved. Radiation models are used for the simulation. Heat transfer is purely due to radiation between the two surfaces.
