當靜態平衡時,在水面以下,靜水壓力隨深度而增加。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氣體滲流傳熱現象,考慮滲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滲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、氣固溫度和床層壓力損失.計算結果表明,高溫熱氣對移動床顆粒料層的熱滲透主要發生在滲流入口端區域,增大入口滲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,熱滲透深度擴大,熱滲透作用區域內的物料溫度水平提高.在熱滲透作用區域,孔隙率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As regards to the spheric thin shell structure under external hydro static pressure, basing on flat - plate theory and by using basic von karman equations for large deflection, the equilibrium problem of axisymmetric bending of the spheric shell under uniform external pressure is simplified to an equilibrium problem of bending of elastic basic flat - plate and further converted into an equilibrium problem of beam on elastic fundation taking into consideration of the deformation characteristics
