Fluid flow velocity
流體流動(dòng)速率
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(duì)移動(dòng)顆粒床中物料層內(nèi)的高溫氣體滲流傳熱現(xiàn)象，考慮滲流與傳熱的相互作用，采用局部非熱平衡假設(shè)建立了多孔介質(zhì)滲流傳熱物理數(shù)學(xué)模型并進(jìn)行了數(shù)值計(jì)算.研究了不同情況下床內(nèi)填充多孔介質(zhì)中的流速、氣固溫度和床層壓力損失.計(jì)算結(jié)果表明，高溫?zé)釟鈱?duì)移動(dòng)床顆粒料層的熱滲透主要發(fā)生在滲流入口端區(qū)域，增大入口滲流速度以及減小床層物料下移速度將導(dǎo)致物料溫度沿床高慢速下降，熱滲透深度擴(kuò)大，熱滲透作用區(qū)域內(nèi)的物料溫度水平提高.在熱滲透作用區(qū)域，孔隙率對(duì)流場(chǎng)和壓力損失有很大的影響.研究結(jié)果對(duì)于移動(dòng)顆粒床反應(yīng)器的設(shè)計(jì)與運(yùn)行具有一定的參考作用
