A tubular heater with a black inner surface of uniform temperature T s = 1000 K irradiates
Question:
A tubular heater with a black inner surface of uniform temperature Ts = 1000 K irradiates a coaxial disk.
(a) Determine the radiant power from the heater which is incident on the disk, qs?1. What is the irradiation on the disk, G1?
(b) For disk diameters of Di = 25, 50, and 100 mm, plot qs?1 and G1 as a function of the separation distance L1 for 0 L1 200 mm.
