This work encompasses different physics involved in fluid flow in shale gas reservoir. Non-linear equations for fluid flow are solved with COMSOL Multiphysics® PDE module. It focuses on comparing the performance of various species transport flux models by accounting for inter-molecular ... En savoir plus
油藏在生产过程中,地层中的孔隙压力下降,压力降由井筒开始向外传播,从而导致地应力场的分布发生变化,后期钻新井的最优位置将因此发生改变,所以必须明确生产过程中油藏地应力场的变化规律。 不考虑储层的温度变化,所建模型只需要进行固体力学与达西渗流场的耦合。对于目前中国的油藏开发情况,地层渗透率较低,单个开发储层较薄,常采用压裂方式增产,将储层看做纵向均质的地层,因此可以使用二维模型。 建立地层为 300m×300m 的矩形区域,井筒为 0.1m 的圆形区域,二者差集为所建的模型。对整个模型区域施加固体力学场和 Darcy 渗流场。因为设置求解应力场为应力的变化量 ...

The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. The optical fiber corrosion sensor based on a side-polished polarizer is realized recently. The polarizer is fabricated by sputtering a Fe film on a side-polished single mode fiber. The new ... En savoir plus
The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to ... En savoir plus
Introduction: Inertial navigation requires acceleration measurement along all three degree-of-freedoms. Most accelerometers are designed to measure acceleration along a single sensitive direction. For complete inertial sensing, a move effective accelerometer which can sense ... En savoir plus
Mutually-soluble solvents can enhance oil recovery both in completely and partially water wet fractured reservoirs. When a strongly or partially water-wet matrix is surrounded by an immiscible wetting phase in the fracture, spontaneous imbibition is the most important production ... En savoir plus
There are various alternative options concerning modeling fluid flow within fractures in porous media. We give a general overview, with remarks concerning the modeling using COMSOL Multiphysics. Moreover we define and study two test cases for intercomparison. Finally for one of the ... En savoir plus
With the development of micro and nanotechnologies, integrated structures based on piezoelectric thin films are widely investigated and their characterization become a crucial issue for the development of new applications. A laser interferometry is here used to assess the mechanical ... En savoir plus
The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir ... En savoir plus
The main reason for stent implantation is to provide mechanical support to the arterial wall. So it is important to consider the different mechanical properties of different stent materials while studying the stent implant’s efficacy. The present study gives a comparative overview of ...
