The Spectral Induced Polarization (SIP) is a promising electrical method, which can be used to predict the saturated hydraulic conductivity of consolidated and unconsolidated porous media. It is important to investigate how the SIP response is affected by the shape and distribution of ... 詳細を見る
The calibration of groundwater models is usually limited by the scarcity of direct hydraulic data. The estimation of heterogeneous distribution of hydraulic properties can be improved through a joint or coupled inversion in which the calibration dataset is complemented with geophysical ... 詳細を見る
Municipal Solid Waste (MSW) landfills typically experience significant settlement associated with various multi-physical factors such as waste property, placement timing, total height, and environmental conditions such as temperature and saturation throughout the lifetime of the ... 詳細を見る
Controlling the odiferous landfill gas (LFG) [e.g., Hydrogen sulfide (H2S)] emission is an important environmental issue during operating a municipal solid waste (MSW) landfill. A combination of LFG collection system and landfill cover has been an adapted method to mitigate the issue ... 詳細を見る
Smouldering is flameless combustion which depends on an exothermic surface reaction occurring within a porous medium. It is harnessed by engineers to destroy organic liquid wastes in soil as the technology Self-sustaining Treatment for Active Remediation (STAR). During this remediation ... 詳細を見る
The frequency dependent electrical impedance of porous media is studied by modelling the charge transport in the electrolyte filled pore space using COMSOL Multiphysics. The corresponding experimental method, called Spectral Induced Polarization (or Impedance Spectroscopy), shows a ... 詳細を見る
优先流作为结构性土壤水分入渗的主要方式，影响着作物对降水以及灌溉用水的利用效率，同时影响污染物在土壤中的迁移过程。虫洞等大孔隙是产生优先流的重要因素，准确评估优先流运动对于土壤入渗的研究具有重要意义。本文主要借助COMSOL Multiphysics软件，探索虫洞的存在对土壤水分入渗的影响。我们结合熔锡灌注法和三维激光扫描法，从田间土壤中提取到真实的虫洞三维结构，然后将真实的虫洞3D结构导入COMSOL5.5中，构建土壤入渗模型。该模型主要用到多孔介质和地下水流模块的理查德方程，其中土体主要由虫洞和土壤基质两部分构成 ... 詳細を見る
We present the results of full-waveform time-dependent finite-element modelling of coupled seismoelectromagnetic wave propagation in fluid-saturated porous media. To describe the seismoelectric response of the system a new set of equations is developed which couple the poroelasticity ... 詳細を見る
Gas shales are one of the potential sinks considered for carbon dioxide sequestration. Therefore further research on the importance of sorption on the carbon dioxide sequestration potential is highly topical. Experimentally measured maximum sorption capacity of carbon dioxide was about ... 詳細を見る
在岩石传热、岩石渗流以及一些和多孔介质有关的领域的仿真中，不可避免的需要用到随机几何。但是三维随机几何建模几乎无法手动完成，必须借助于程序自动建模。利用comsol的API接口结合Java语句可以实现这一功能。在comsol的app开发器下的方法中能够进行代码的编辑。具体创建思路如下：假定物体为一个111的块体，然后在块体中生成位置随机、角度随机的椭球体。随机性可以用random函数保证，但是这样生成的椭球会重合。为了保证生成的椭球不重合，需要先生成第一个随机椭球，并添加进累积选择中(CumulativeSelection)，然后将累积选择 ... 詳細を見る
