Consider the heat equation
dT/dt - aΔT + v⋅∇T = S
where S is a source term dependent of the radiation intensity I and the temperature T. The fluid velocity v is prescribed.
We also consider the radiative transfer equation describing the radiative intensity I(x,ω,t) where ω is the ray direction.
The boundary Γ consists of three parts: solid walls Γ1, inflow part Γ2 and outflow part Γ3. The domain Ω may be, for example, a rectangular channel.
What boundary conditions for T should we specify on Γ2 and Γ3? What BCs are the most natural? Please give a reference if possible.
What boundary conditions can be specified for I on these parts?
