Consider two large (infinite) parallel planes that are diffuse-gray with temperatures and emissivities of T 1 ,
Question:
Consider two large (infinite) parallel planes that are diffuse-gray with temperatures and emissivities of T1, ?1 and T2, ?2. Show that the ratio of the radiation transfer rate with multiple shields, N, of emissivity ?s to that with no shields, N = 0 is, where q12, N and q12, O represent the radiation heat transfer rates for N shields and no shields, respectively.
