Consider a cone shaped cavity of opening size (D) of 12 mm and 30 mm in depth (L) is
machined on a diffuse, gray block having an emissivity of 0.7 and a uniform temperature
of 1000degree
C.?e of a cavity is defined as the ratio of the radiant power?e as a function of L/D over a range
(a) Determine the view factor between the inner surface of the cavity and the opening of
the cavity.
(b) The effective emissivity
leaving the cavity to that from a blackbody having the area of the cavity opening and
a temperature of the inner surfaces of the cavity. Calculate the effective emissivity of
the cavity described above.
(c) For wall emissivities of 0.5, 0.7, and 0.9, plot
from 1 to 10.
