The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship [1]. One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers [2]. They ... En savoir plus
THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and ... En savoir plus
The effect of static magnetic fields (SMF) on living matter such cell cultures and living organisms has been a promising research field. Efforts have been given in the understanding of the underlying mechanisms and interaction between the field and the biological system with its ... En savoir plus
This study explores the significance of the recoil pressure, Marangoni convection and surface tension effects in selective laser melting of Ti-6Al-4V. A pragmatic two dimensional model with appropriate powder distribution over a substrate of finite thickness has been developed in COMSOL ... En savoir plus
Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is ... En savoir plus
An energy pile harvests geothermal energy to heat and cool a building by integrating ground heat exchanger (GHX) pipes into the building’s deep foundation, and extracts heat from the ground in the winter to heat buildings and injects heat into the ground during the summer. In areas with ... En savoir plus
Droplet generation in microfluidics is a powerful technique to get monodispersed emulsions and droplet size manipulation can be very advantageous in a wide area of applications such as pharmaceuticals, drug delivery, food products, chemical synthesis and biomedical applications. In the ... En savoir plus
The ongoing trend towards miniaturization, higher integration as well as cost efficiency will make it necessary to investigate a new assembly method for micro components. In this paper, a novel method of fluidic-based micro assembly is presented. A self-assembly effect which is caused by ... En savoir plus
借助数值模拟技术及煤层气排采经验分析排采过程中流体流动运移规律,能够为煤层气井智能排采提供技术支持。本文以某煤层气井地质与开发工程为基础,借助COMSOL软件构建求解数值模型,实现了煤层气排采动态分析及排采制度优化。取得以下主要研究成果: (1)采用含压裂裂缝的Warren-Root物理模型,以达西渗流理论知识为基础,建立了封闭可求解的煤层气排水降压数学模型。 (2)利用二维面和三维长方体叠加的混合法构建压裂裂缝,利用混合法求取边界流量,解决裂隙通量计算误差,提高了计算效率和流量统计准确率。 (3)以参数化扫描研究方法为基础,优化了该井的排采制度 ... En savoir plus
An external library, M4Dlib [1], has been developed to solve multiphysics problems coupled to solution thermodynamics. This approach extends the local equilibrium concept[2] to multiphysics modeling by incorporating a full Gibbs energy minimization routine at each numerical node to ... En savoir plus
