Solution of Radiative Heat Transfer in 2-D Geometries by a Modified Finite-Volume Method Based on a Cell Vertex Scheme Using Unstructured Triangular Meshes

Combined conductive and radiative heat transfer in an anisotropic scattering participating medium with irregular geometries

“…Asllanaj et al [5] proposed a new FiniteVolume Method (FVM) based on a cell vertex scheme, associated to a new modified exponential scheme to solve the radiative heat transfer problem in 2-D irregular geometries containing absorbing, emitting and non-scattering gray media.…”

Conduction and radiation in a rectangular isotropic scattering medium with black surfaces by the RTNAM

“…So, in 2004, using discrete transfer method (DTM) in combination with unstructured triangular meshes, Feldheim and Lybaert [19] studied radiative heat transfer in rather complex-shaped domains, such as quadrilateral cavity, L-shaped cavity and eccentric cylinders, and the ray effect of the DTM was studied. In 2007, they further developed a new FVM based on a cell vertex scheme and associated to a modified exponential scheme to study radiative [20] and transient coupled radiative and conductive [21] heat transfer in above complex-shaped domains as well as in cylindrical ring and elliptical ring domains, and in order to simplify the problems, the boundaries of those complex-shaped domains were considered to be black. In the work of Sakami et al [22], the DOM was modified and applied to the study of coupled radiative and conductive heat transfer in semitransparent enclosures of arbitrary geometries.…”

Highly-Directional Radiative Intensity in a 2-D Rectangular Enclosure Calculated by the DRESOR Method

“…Since the spatial domain is divided into a finite number of control volumes in DOM and FVM, these methods have a computational compatibility with other control-volume based computational fluid dynamics (CFD) approaches. In most cases applied by these methods, only the radiation flux or its dimensionless quantity was considered [6][7][8][9][10][11]. The angular distribution of intensity with highly-directional resolution must be measured in most inverse radiative transfer problems [12][13][14][15], for example, monitoring of temperature distributions in industrial combustion furnaces by flame image processing techniques [15].…”
