Abstract
The radiative heat transfer in axisymmetric cylindrical media and the rectangular ideal furnace are studied by means of the finite volume method (FVM). Compared with the results of the Monte Carlo (MC) method and the discrete transfer method (DTM), the reliability of our FVM code is proven. At the same time, the influence of different grid schemes (FVM1, FVM2 and FVM3) on the temperature field precision, incident flux, radiative net flux and computational time in cylindrical absorbing and scattering media are analyzed, respectively. The relationship between solid angle discrete schemes (FA1, FA2 and FA3) and the precision are studied as well. The results show that the FA3 solution is more accurate than FA1 and FA2. FA3 is therefore suggested for use in calculating the radiative heat transfer by FVM.
