Radiation Heat Transfer an overview ScienceDirect Topics

Radiation heat transfer. The radiation heat transfer between two parallel planes is reduced by placing a parallel aluminum sheet in the middle of the gap. The surface temperatures are θ 1 = 40 °C and θ 2 = 5 °C, respectively the emissivities are ε 1 = ε 2 = 0.85. The emissivity of both sides of the aluminum is ε a = 0.05. Calculate by
