  1. In this paper, high heat penetration into a moving particulate bed is described mathematically with a comprehensive heat and mass transfer model. the distribution of gas velocity and pressure, the temperature field of gas and solid in the moving particulate bed are examined for different conditions. the results show that thermal penetration into the moving packed - bed particles by fluid flow in porous media is high only in the position near the gas entrance. the thermal penetration thickness tends to increase with the fluid flow velocity and decrease with the particle moving velocity. in the region of thermal penetration, the porosity of solid bed has significant effect on gas field and pressure loss. it is feasible to reduce the gas pressure loss by a larger width / height packed bed in design and operation. the correspondence between thermal infection depth and particle bed height would be helpful to keep high oapacity of reactor and reduce the cost of operation

    針對移動顆粒床中物料層內的高溫流傳熱現象,考慮流與傳熱的相互作用,採用局部非熱平衡假設建立了多孔介質流傳熱物理數學模型並進行了數值計算.研究了不同情況下床內填充多孔介質中的流速、固溫度和床層壓力損失.計算結果表明,高溫熱對移動床顆粒料層的熱主要發生在流入口端區域,增大入口流速度以及減小床層物料下移速度將導致物料溫度沿床高慢速下降,熱深度擴大,熱作用區域內的物料溫度水平提高.在熱作用區域,孔隙對流場和壓力損失有很大的影響.研究結果對于移動顆粒床反應器的設計與運行具有一定的參考作用
