iCP (Nardi et al, 2014) is a software that couples two standalone simulation programs: COMSOL Multiphysics® and PHREEQC (Parkhurst & Appelo, 2013). The tool is ideal for applying multiphysics and geochemistry in Earth Sciences. Flexibility of the two coupled codes result in an ... 詳細を見る
Sintering is an important step in the manufacturing of polytetrafluoroethylene (PTFE) billets. The challenge in heating large billets stems from the inherent low thermal conductivity of PTFE. Existing literature suggests determining maximum heating rate experimentally using recommended ... 詳細を見る
干热岩致密且天然裂缝发育，能否有效激活天然裂缝、提高储层连通性是高效开发干热岩地热能的关键。流-固-热耦合作用下的裂缝剪切滑移机制是其关键科学问题之一。本文基于 COMSOL 多物理场计算平台，建立干热岩压裂裂缝剪切滑移模型，综合考虑热储层与注入流体换热、原地应力、缝内净压力、裂缝面摩擦系数等原位参数，得到了裂缝剪切滑移加速度与位移、速度与位移、位移与时间以及摩擦力与位移的变化规律。同时研究了材料属性、法向加载路径、切向载荷和摩擦系数等因素对极限滑移距离的影响规律。结果表明：裂缝极限滑动位移（极限滑动距离）受岩石弹性模量、裂缝面摩擦系数 ... 詳細を見る
A dual axis MEMS seismometer targeted for building monitoring system has been simulated for a full scale of ±5g acceleration. The design uses the capacitive effect for vibration sensing. This comb drive capacitive MEMS seismometer consists of 8 springs with two proof masses. The device ... 詳細を見る
The authors present a closer look on the Single-Well Injection-Withdrawal Experiment (SWIW) or Push-Pull Experiments and its ability to determine the groundwater velocity, as one of the major parameters concerning reservoir management and underground reservoir characterization. The flow ... 詳細を見る
A common clinical treatment is the application of alternating electromagnetic fields using a screw implant to the weak bone tissue within the femoral head, which speed up the bone regeneration in case of avascular necrosis of the femoral head . In our present work the bipolar induction ... 詳細を見る
In this paper, a free membrane is used as a receiver to increase the capacitance and therefore the resolution of the flow meter. For the current application, from the wavelength of sound wave in soft tissue (c= 1540 m/s) the resolution was calculated to be 0.48 mm. This gives the first ... 詳細を見る
This paper presents a freestanding waveguide to achieve the goal of detecting anastomosis leakage after colon surgery. The freestanding part is a thin membrane consisting of TiO2 rib and SiN ridge. This freestanding waveguide is designed both mechanically and optically to maintain ... 詳細を見る
The Geoenvironmental Engineering Group of the University of Castilla-La Mancha is developing a computational tool, M4B, for describing the influence of environmental loads on the deformation behavior of soils and its interaction with building foundations. This tool comprises a set of ... 詳細を見る
Silicon electrodes are presently being pursued as the potential negative electrode for lithium-ion batteries owing to its high gravimetric (mAh/g) and volumetric capacity (mAh/L) compared to the existing state of the art graphite electrode. Recent experimental studies have demonstrated ... 詳細を見る
