Abstract
In the present study, an original three-dimensional formulation of the FT
n finite volume method based on the bounded high-resolution CLAM schema and using the blocked-off-region technique has been developed. Firstly, this model is applied for 3D inhomogeneous L-shaped absorbing/emitting and isotropically scattering media. Both isothermal medium and medium with internal uniform and non-uniform volumetric heat generation are considered. Secondly, the present FT
n FVM results for 3D combustion chamber with five baffles are illustrated and discussed. All tests bring to the fore the advantages, in 3D problems, of the FT
n FVM comparatively with the standard FVM especially for inhomogeneous media with discontinuous volumetric heat sources. However these benefits still quantitative and no qualitative discrepancy between the FT
n FVM and the popular FVM results are registered.
