Analyzing thermal radiation in cylindrical anisotropic scattering medium with element differential method

The spontaneous radiation combustion diagnosis technology has high requirements for obtaining the intensity of highly directional resolution in a system. Taking advantage numerical stability and easy implementation element differential method, this paper constructs model that can achieve spatial angular high-resolution cylindrical anisotropic scattering medium. In analyzing model, is discretized three dimensions. An upwind scheme proposed to suppress oscillation strong convection characteristics transfer equation. double-layer node algorithm used capture discontinuous singularities at boundary. comparison with analytical solution shows based on method description high-order accuracy. accuracy validity are verified through comparing results Monte Carlo method. further three-dimensional distribution angle space proves up-wind effectively realize stable calculation.
