The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these ... 詳細を見る
“页岩气革命”使美国成功摆脱了对他国能源的严重依赖,目前我国页岩气的勘探开发也已取得了突破性成果,但是随着页岩气的开发,仍存在三大问题困扰着科学工作者和现场工程师:(1)页岩气开发过程中的渗透率演化规律尚未摸清;(2)在产气过程中,页岩气在产量上往往呈现出不确定性;(3)缺乏针对页岩气进行历史拟合和产量预测的数学工具。针对以上三个主要问题,我们定义非常规储层固有渗透率的演化是裂隙和基质之间物质传输和应力传递的结果,并建立了离散体模型研究孔隙变形与流体流动之间的耦合作用;以此为基础,我们建立双基质双重孔隙介质模型(连续介质模型)研究页岩基质变形与流体流动之间的耦合关系 ... 詳細を見る
Presented work is motivated by pre-realization phase of rock heating experiment in underground, testing properties for cyclic energy storage. Heating unit, installed in large borehole from end of a tunnel, is fixed to the rock face with the geo-polymer. Rest of the borehole is filled ... 詳細を見る
This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which ... 詳細を見る
One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and ... 詳細を見る
In general, macroscopic two-phase flow in porous media is a mixture of connected and disconnected oil flow. The latter is expressed as ganglion dynamics and drop traffic flow, patterns observed experimentally in pore network models [1,2] and real porous media [3,4]. This characteristic ... 詳細を見る
A mathematical model for the simulation of contaminant such as heavy metals removal from soils by electric fields was performed in a 2-D geometry using COMSOL Multiphysics. Electrokinetic phenomena is the result of the coupling between hydraulic and electrical potential gradients in ... 詳細を見る
In a soil pore, water flows through the biofilm, where the density of the latter was assumed to represent a flow resistance. This mechanism was implemented as a local change of fluid viscosity proportional to local biofilm density. It was assumed that diffusive substrate transport is ... 詳細を見る
The problem is to understand how a geothermal field can evolve from a water dominated state into a vapor dominated one. A first answer to this question is given by a simplified mathematical model of the dynamics of a geothermal field in which the geothermal fluid is entirely composed by ... 詳細を見る
In this paper, an integrated model for ocean waves propagating over a submerged coastal structure, based on COMSOL Multiphysics, is presented. In the model, Navier-Stoke Equation is solved for the wave propagation and Biot’s poro-elastic model is solved for the porous seabed. The new ... 詳細を見る
