Prediction of Radiative Transfer in General Body-Fitted Coordinates

Inverse radiation analysis using repulsive particle swarm optimization algorithm

“…The non-radiative volumetric heat source is _ Q ¼ 5:0 kW=m 3 . The walls are gray and their temperatures are all T w = 1000 K. The spatial and angular domains are discretized into (N x  N y ) = 10  10 control volumes and (N h  N / ) = 4  20 control angles corresponding to S 8 quadrature scheme [21]. The temperature distribution in gray gas is determined from the following energy equation [22]:…”

Estimation of emissivities in a two-dimensional irregular geometry by inverse radiation analysis using hybrid genetic algorithm

“…In complex geometry, the discrete ordinate method (DOM) and the ÿnite volume method (FVM) are usually used to solve radiative transfer equation. Liu et al [19] recommended the use of the FVM, which has advantages in selecting control angles and guaranteeing conservation of radiant energy, even though DOM and FVM are accurate and e cient in complicated high-temperature combustion systems.…”

“…The nonradiative volumetric heat source isQ = 5:0 kW=m 3 . The walls are gray walls, and their emissivities and temperatures are all w = 0:7 and T = 1000 K. The spatial and angular domains are discretized into 10 × 10 control volumes and 4 × 20 control angles which corresponds S 8 quadrature scheme [19]. The temperature distribution is determined from the energy equation [21].…”

The combined Monte-Carlo and finite-volume method for radiation in a two-dimensional irregular geometry

“…Among others, there is the ®nite-volume method (FVM) for radiation [1,2] which has been successfully applied to several problems of body-®tted geometries [3,4]. In the meanwhile, the discrete ordinates method (DOM) was also extended to handle a body-®tted geometry, and its computational accuracy has been discussed [5]. Since the spatial domain is divided into a ®nite number of control volumes in the DOM and FVM, these methods have a computational compatibility with other controlvolume based CFD approaches.…”
