关键词： 纺织品   耐光   化纤  

摘要： 耐光照射两阶段耗时较长,如果能使用一阶段照射代替两阶段照射,可以缩短检测周期。文章对化纤类纺织品耐光两阶段进行分析,发现化纤包氨纶结构是造成化纤类纺织品耐光两阶段变化较大的主要原因。在耐光照射时,对于一般结构的化纤,可以使用一阶段照射,从而缩短检测周期。

关键词： Adjoint-based shape optimization   CAD parametrization   Fin design   Heat sinks  

摘要： This study presents an automated shape optimization method for heat sinks. The computational framework has been developed by combining a conjugate heat transfer solver with adjoint capabilities, a CAD parametrization tool, and a gradient-based optimizer. The test case considers the design optimization of a water-cooled heat sink with pin fins, with the goal of concurrently enhancing heat transfer and minimizing pressure losses. Results show that the optimized fin geometry leads to an improvement of the average heat transfer coefficient by 24% while the pressure drop is lowered by 19%. The optimal fin array features an unconventional shape with an enlarged cross-section at the hub and the top with respect to mid-span, and a variation of the pin profile in the streamwise direction. The net effect is a reduction in flow blockage, an increase in fin efficiency, and a lower and more uniform temperature distribution in the heat sink base plate.

关键词： 针织物   黏附性能   黏附力   剥离高度   剥离速度   测试分析  

摘要： 为研究针织物湿态下黏附力的变化情况,文中设计一种可测量针织物湿态黏附力的装置,测试不同剥离速度下针织物的最大黏附力、达到最大黏附力时的剥离高度、织物干湿比、织物实际接触面积4项指标。结果表明:在一定范围内,织物的最大湿黏附力随剥离速度增大呈现先增大后减小并逐渐趋于稳定的趋势,500 mm/min左右的剥离速度是探究湿黏附力变化的最佳数值;织物达到最大湿黏附力时的剥离高度与织物的干湿比呈负相关,与实际接触面积呈正相关;织物最大湿黏附力受含湿量和实际接触面积影响,其本质由织物物理参数决定,在其他条件相近时,纯棉织物的湿黏附力大于纯涤纶织物,双面织物的湿黏附力大于单面织物,纬平针类织物的湿黏附力大于珠地类织物。

关键词： CAD   Complex geometries   Curvilinear   High-order   Industrialisation   Mesh generation   Spectral/hp element methods  

摘要： Established a posteriori mesh generation, high-order mesh curving and some mesh optimisation approaches often rely on an accurate CAD parametrisation of the boundary of the computational domain. This information, however, is not always available, especially when composite multi-software workflows are employed. To deal with such cases, we propose a method for reconstructing the missing connectivity information between the mesh and the CAD geometry when importing an arbitrarily sourced mesh. The reconstruction is followed by curving methods for order elevation, projections or subsequently optimisations with boundary-conforming node sliding. Lastly, mesh modification techniques are used to achieve the desired mesh resolution and quality for meshes incorporating boundary layers. We illustrate the steps of the proposed end-to-end workflow through two simple geometries coming from different sources and an end-to-end complex automotive mesh generation test case.
