摘　　要：在假定透明蜂窝壁面具有漫发射和漫反射性质的基础上对大孔径复合透明蜂窝中的对流、导热和辐射的耦合传热进行了分析。研究了吸热板的发射比、蜂窝孔的高宽比、宽度等参数对热损系数的影响，并讨论了蜂窝孔内的自然对流情况。A numerical simulation to study the heat loss coefficient of compound honeycomb with a large diameter is carried out using the coupled natural convective and radiative heat transfer model.The influence of absorbers emissity ε p,cell diameter D and cell aspect ratio L/D on the heat loss coefficient across a compound honeycomb are discussed and the natural convection in honeycomb cell are investigated.
