The major works are as follows: 1 The 3-D numerical model of U-sharp flow passages is set up. The single-phase fluid flow and heat transfer are simulated for the U-sharp smooth and rib-roughened flow passages with FLUENT software. Their performance curves, temperature field and velocity vector are obtained and the local heat transfer and flow pressure-drop distribution along flow passage are analyzed. It is revealed that the ribbed flow passages can enhance heat-transfer and make the temperature more uniform, but it increases the pressure-drop to more extent. 2 The influences of diaphragm depth, channel width and board spacing on the performance are investigated.

建立了层叠式蒸发器U形流道的3维湍流模型，用FLUENT软件对尺寸相同的U形光滑流道和肋化流道中单相流体的传热和流动进行了数值模拟，得到了两种流道的传热和阻力性能关系曲线及速度矢量图、温度场，分析了光滑流道和肋化流道的局部换热系数及沿程压降变化，结果表明流道的肋化能有效的增强传热，而且使流体的流动和传热更加均匀，但也较大地增大了阻力。

The results of cold-flow model test indicate:(1) the pressure drop rises with increasing air quantity and solids quantity respectively, however, much more air quantity and solids quantity minish in the same height position;(2) the pressure drop rises with increasing solids quantity;(3) the average granule concentration minishes with increasing air quantity, and rises with increasing the granule quantity in the same level position;(4) the inhomogeneity of distribution granule concentration minishes with increasing air quantity, and rises with increasing the granule quantity in the same level position.

结果表明：(1)在同一高度截面上，循环流化床反应器炉膛内压降随风量的增加而增加，但是风量过于增大反而使压降在同一截面上减小；(2)压降随初始物料量的增加而增加；(3)在同一水平截面上，颗粒浓度随风量的增大而逐渐减小，随物料量的增大而增大；(4)颗粒浓度分布的不均匀性随风量的增大逐渐减小，随物料量的增加不断增大。
