Chemical Engineering > GATE 2015 > Radiation Heat Transfer
Two infinitely large parallel plates (I and II) are held at temperatures Tβ and Tβ (Tβ > Tβ) respectively, and placed at a distance 2d apart in vacuum. An infinitely large flat radiation shield (III) is placed in parallel in between I and II. The emissivities of all the plates are equal. The ratio of the steady state radiative heat fluxes with and without the shield is:
