摘要
通过DRESOR(d istribu tions of ratios of energy scattered or reflected)法求解一维黑体边界发射、介质各向异性散射的辐射传递问题,与理论解、辐射元法、蒙特卡洛方法和有限体积法的计算结果进行比较,验证了该方法计算的准确性;同时,对DRESOR法给出的高方向分辨率的辐射强度进行了分析。计算了带有漫反射边界介质具有吸收、发射、各向异性散射特性的辐射传递问题,对不同工况下的辐射强度和辐射热流进行了比较分析。
DRESOR （distributions of ratios of energy scattered or reflected） method was applied to solve the radiative transfer equation for anisot Comparing the results with the existing exact ropic scattering media with solution, radiative element black boundary emission. method, the Monte Carlo method and the finite volume method, it is shown that the results of DRESOR method are reliable. Furthermore, the intensity with high directional resolution in any point was obtained by DRESOR method. Also, the radiative transfer equation for the emitting, absorbing, anlsotropic scattering gray media with diffusely boundary condition was solved and the results of radiative intensity and radiative flux was analyzed for different cases
