摘要：The Printed Circuit Heat Exchanger(PCHE) is one of the most promising heat exchangers for Synergetic Air-breathing and Rocket Engine(SABRE). To reduce pressure drop and improve compactness, the micron-sized PCHE made up of rectangular channels of tens of microns in size, is used in SABRE. In present work, we focus on thermal-hydraulic-structural characteristics of micron-sized PCHE by conducting three-dimensional(3-D) numerical simulation. Helium and hydrogen are employed as the working fluids and the Stainless Steel 316(SS316) as the solid substrate. The thermal-hydraulic performance of the micron-sized PCHE is discussed by using the commercial Computational Fluid Dynamics(CFD) software of Fluent. ANSYSMechanical is also employed to simulate stress field of representative PCHE channels. The mechanical stress induced by pressure loading and the thermal stress induced by temperature gradient are found to be equally important sources of stress. To improve comprehensive performances of micron-sized PCHE, two types of channel arrangements and different channel aspect ratios are studied. The double banking is of higher thermal-hydraulic performance compared to the single banking while the stress performance is identical for the two modes. Meanwhile, the effect of channel aspect ratio is investigated by comparing thermal-hydraulic characteristics and structural stress of the model. The rectangular channel with w/h=2 achieves the most balanced stress characteristic and higher thermal-hydraulic performance.

摘要：植物是园林中唯一有生命的要素,是园林生态系统中唯一的生产者,是生态文明建设的基石。与植物规划设计有关的名词比较多,包括种植设计（Planting design）、植物配置（plant arrangement）、植物造景（plantscaping）、植物景观设计（plantscape design）等。或许各个名词的侧重点不一样,各人的偏好也不一样,但实质上是相同的。我们《现代园林》

摘要：项目地址澳大利亚墨尔本设计单位Andrew Maynard Architects这是一栋由新旧两个部分组成的名为Barrow的住宅。新的部分从外形上看更像是由多个不同的木制盒子组合起来的建筑,每个独立的"盒子"彼此相嵌,紧密地拼接在一起,所以外部的形状显得不太规则,而且也导致内部形成多个体积不尽相同的空间单元。而旧有的部分则是一个规规矩矩的长方体盒子,两者在外形上形成了新旧之间的鲜明对比。

摘要：SIA青山大楼是一座用于出租的高层办公楼,位于集聚了日益增多的品牌店铺及涩谷站的表参道商业区中心。区域内混合并置着许多住宅与办公地块。因此,这座建筑在设计时并未把自身归于这两种类型的任何一种之中;一座高塔般的庞然大物,有着无缝衔接的光洁表皮。建筑本身高64m,自地面层算起共有9层,天花板高度相对较高,达4.9m。
