This study presents the simulation of transport phenomena in the Horstberg geothermal system in the North German Basin. The Horstberg geothermal system composed of a subsurface reservoir and a borehole. The borehole was completed in a multilayer sandstone reservoir and an induced ... Read More
The unconventional shale gas reservoirs have a major contribution to hydrocarbon production in recent years. The hydraulic stimulation technique is being used to enhance the productivity of the target reservoirs. The drilled wellbore and existing natural fractures in the host rocks have ... Read More
Finite element modelling of surgical transducers has been performed and is described. Ultrasonic transducers vibrating at around 25 kHz are used in orthopaedic surgery to cut bone. The high acoustic impedance of the metal blades used in these devices couples energy more efficiently to ... Read More
Hydraulic fracturing, or fracking, is a technique used to extract oil and gas in shale rock. A mixture of water, sand, and chemicals are pumped into the well at high pressures to keep the fissures open, which allows the gas to flow. Although intermediate casings are inserted into the ... Read More
Through Silicon Via (TSV) is one of the key technologies for 3D integration. It is a vertical electrical connection that passes through a silicon wafer and establishes the signal transmission between the front and the backside of the device. In the so-called “TSV last” integration ... Read More
In fractured reservoirs, much of the oil is stored in low permeable matrix blocks that are surrounded by a high permeability fracture network. Therefore, production from fractured reservoir depends on the transfer between fracture and matrix, which is critically dependent on their ... Read More
The consequences of hip fracture and femoral fracture are widely known. The mechanical strength of the femur varies in every person, but it is possible to predict the mechanical resistance with parameters like density, dimensions and mineral content. This paper uses different models and ... Read More
气体渗流机制和渗透率演化是预测页岩储层天然气产量的重要因素。本文建立了多场耦合下的基质和裂缝的动态渗透率演化模型，并将其整合到COMSOL求解器中，并利用岩土力学和地下水流模块求解。此外，分析了基质收缩和应力敏感性对渗透率的影响。研究结果表明，孔径增大会增加页岩储层的气体渗流能力。与常规储层相比，由于气体多重流动机制，在小孔（1-10 nm）和低压（0-5 MPa）下，基质表观渗透率与达西渗透率之比高出约1-2个数量级。流动机制主要包括表面扩散，努森扩散和滑移流动。同时基质收缩和应力敏感性的综合影响导致纳米孔闭合，与基质初始渗透率相比，渗透率下降约1个数量级 ... Read More
It has been well proved that hydrogen represents a harmful element for steels because it can easily embrittle them. This phenomenon is known as Hydrogen Embrittelement (H.E.) and it leads to a serious decrease in mechanical properties especially loss of ductility. The studied material is ... Read More
Groundwater is a key factor affecting mine operations worldwide. On one hand, both underground and open pit mines need to pump out groundwater in order to proceed with mineral extraction and increase the stability of rock slopes. On the other hand, groundwater abstractions can produce ... Read More
