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。
