| 摘 要： | 本介绍了单相流体在多孔介质内部的传热和流动过程及其研究方法，给出单相流体大多孔介质内部传热的数理模型，对模型的有效性进行了验证。同时分析了流速、孔晾率、固体颗粒的直径大小及固体骨架和流体的导热系数之比等因素对多孔介质内部传热和流动的影响，提出了增加传热而不使流动阻力过多增加的方法．

| Abstract: | The mechanism and the research methods of convection heat transfer and flow for mono phase fluids in porous me dia are introduced.The mathematic models of flow and convection heat transfer ar e given and tested experimentally.The ef fects of several factors on heat transfe r and/or flow,such as flow rate,porosity ,the diameter and the conductivity of so lid spherical beads,are analyzed.The met hods that can increase heat transfer wit hout causing flow resistant to be increa sed too much are suggested,too. |
