This analysis evaluates the importance of the lateral component of flow on the infiltration of water from parallel strip sources of water on the soil surface. Flow from such sources will be two-dimensional, having both vertical and lateral components. Here we examine the effect of the ... 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
Pyrometallurgical furnaces are used to produce metals such as copper, nickel and platinum by the smelting process. During smelting, the undesired material components are separated from the desired metal resulting in the formation of a slag and matte/metal phase. The slag phase ... Read More
冻融循环引起的破坏是季节冻土区渠道的主要病害，其发生与温度梯度和水分迁移有密切的联系。为了研究冻融循环作用下土体温度变化与水分分布，多场耦合理论应运而生。但目前存在的多场耦合模型大多采用了过多的参数，其中的一些参数甚至难以确定。因此本文基于Harlan流体动力学模型，以温度和孔隙率为变量建立了一个实用的多场耦合控制方程，然后采用COMSOL Multiphysics中的数学模块中的系数型偏微分方程（PDE）对土体温度场和水分场进行模拟，并与室内水分迁移试验进行对比，证明了该耦合模型的有效性。最后以北部引嫩工程渠道为例，建立模型试验，所得试验结果与模拟结果也是十分接近。 Read More
A comprehensive three dimensional finite element thermal model has been developed using COMSOL Multiphysics® software to understand the thermo-physical behaviour of the uppermost regolith layer of the moon. The model can simulate variable layers, layer thickness and dimensions and can ... Read More
Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of ... 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
Electric, magnetic and electromagnetic (em) methods are widely used to monitor active volcanoes. A review of such applications is presented in Johnston (cit). Em signals were recorded in correspondence of numerous volcanic eruptions, for example in the case of the Mt. Unzen in Giapppone, ... Read More
The Marine Controlled Source ElectroMagnetic (marine CSEM) is a geophysical method used by the oil industry to investigate resistive targets in the sediments under the ocean floor. In this work we simulate marine CSEM data including 1D, 2.5D and 3D modeling. The results obtained with ... Read More
