为研究不同加热方式下煤岩内部裂隙在热力耦合作用下的变形特征，建立了微波和常规加热两种数值模型，考查了不同温度场分布特征下裂隙周边应力应变场的变化过程。研究结果表明：微波加热，温度场分布具有内高外低的特征，此时裂隙周边分布的应力多为压应力，且数值较大，裂隙边界位移表现为向内收缩；常规加热，温度场分布具有外高内低的特性，此时裂隙周边分布应力多为拉应力，但量值较低，裂隙边界位移表现为向外扩张；热源越靠近裂隙压应力越明显，反之拉应力明显。 Read More
Electrical resistivity surveys have been used for many decades in hydro geological, mining and geotechnical investigations. Various types of electrode combinations have been tested. But different array gives different type of response over same sub-surface feature. Response of different ... Read More
2015年由美国大发起页岩气革命成功地使美国从油气进口国转变为油气出口国。这使得页岩气成为能源领域关注的热点。页岩气与煤炭和石油相比更为清洁，且储量更为丰富。开发页岩气的两项关键技术是水平井钻井技术和压裂改造地层技术。 然而，由于页岩相比于其他岩石水化学活性更强，导致在水平井钻穿储层过程中井壁极容易垮塌失稳。油基泥浆的使用可以克服上述问题，但成本昂贵且受环保限制。水基泥浆的普及依赖于对页岩水化的深入理解。在页岩水化反应过程中，温度场、离子浓度场、渗流场、应力场均不同程度地作用在井壁周围岩石，而且相互耦合作用随时间不断变化 ... Read More

Disposal in deep clay geological formations is one of the promising options for disposal of high-level radioactive waste. Yet, they can generate considerable amounts of heat as a side effect of radioactive decay. This paper shows how COMSOL Multiphysics has been used to evaluate the ... Read More
The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by ... Read More
鉴于煤岩体“孔—裂隙”双重介质属性，利用COMSOL软件建立了含有孔、裂隙结构的煤岩基质细观结构模型。在模型中采用固体力学模块、层流模块、达西定律模块以及稀物质传递模块，通过自定义参数耦合和边界耦合的方式实现了多物理场的相互耦合作用。针对不同裂隙入口气压情况进行了数值模拟计算和分析，结果表明在裂隙壁附近应力过渡明显，渗透率变化显著，极易发生损伤破坏。研究发现模型中存在某一临界位置，在其两侧渗透率随入口压力的变化规律相反，即模型中距裂隙边界一定范围内的煤岩基质渗透率随入口压力的增大而逐渐减小，但在此范围外的煤岩基质渗透率随入口压力的增大反而逐渐增大 ... Read More
Anticipation of meteorological events such as ice forming is a key challenge to optimise the use of antifreeze on airport runways. To obtain a predictive numerical tool of ice forming on the runways, Groupe ADP and SIMTEC developed a COMSOL Multiphysics® model, in which several physical ... Read More
Renewable energies generate temporary mismatches between energy demand and supply. The conversion of surplus energy to hydrogen and its storage in geological formations is one option to balance this energy gap. Storage in deep saline aquifers is the most cost-effective option for ... Read More
