O. Manca et V. Naso, SOLUTION TO STEADY-STATE 3-DIMENSIONAL CONDUCTION FOR A RECTANGULAR SURFACE HEAT-SOURCE ON A SEMIINFINITE BODY, International communications in heat and mass transfer, 21(6), 1994, pp. 799-808
The solution to the steady-state three-dimensional problem in a semi-i
nfinite body due to a rectangular surface heat source is derived. Some
results, in terms of temperature distribution in significant planes,
for a rectangular and a square spot are presented. Maximum temperature
s as a function of depth and size of the spot are also reported.
