摘要: This article deals with the application of modified discrete ordinate method (MDOM) to calculate volumetric radiative information and without conduction in a concentric spherical enclosure containing participating medium. With known from MDOM, energy equation combined mode transient radiation heat transfer is formulated solved using lattice Boltzmann (LBM). Without conduction, for pure case, two benchmark problems, representing nonradiative equilibrium situations are taken up. In case non-radiative equilibrium, an isothermal medium bounded by cold walls source radiation, while nonisothermal confined between hot wall, (inner sphere) wall source. Depending upon problem, flux, flow rate, emissive power, temperature distributions calculated differen...
