Heat radiation mechanism. Heat radiation mechanism (a) The radiative heat flow mechanism, where total exitance or radiosity equal to the sum of reflected radiation W r = ε . σ . T r 4 , transmitted radiation W t = ε . σ . T t 4 and emitted radiation W e = ε . σ . T e 4 , (b) The concept of impinging the process of radiation on a target surface, where (1) is the total radiant energy, (2) heat source,(3) absorbed energy, (4) reflected energy, (5) transmitted energy, (6) total detected energy and (7) total surface properties (© MedIT, 2011).
