研究高温固定床壁面或埋设平板表面附近受迫对流换热；计算结果表明当对流－辐射参数或传导－辐射参数减小，或雷诺数增加时辐射换热速率随之增加；辐射对导热、对流的影响由颗粒所吸收的净辐射能的符号所决定；床和平板的辐射特性及热流方向对传热也有影响。 The results show that when the convection-radiation parameters or conduction-radiation parameters decrease or the Reynolds number increases, the radiation heat transfer rate increases. The effects of radiation on heat transfer and convection The effect is determined by the sign of the net radiant energy absorbed by the particles; the radiation characteristics of bed and slab and the direction of heat flow also have an effect on heat transfer.
