Seismic evaluation of existing dams is a major issue that has been even more highlighted by the recent events in Italy. In this regard, researchers and engineers need a reliable and quick tool to assess the complex behaviour of the structure – fluid – soil system. In this paper the soil ... Per saperne di più
Hydraulic fracturing, or fracking, is a technique used to extract oil and gas in shale rock. A mixture of water, sand, and chemicals are pumped into the well at high pressures to keep the fissures open, which allows the gas to flow. Although intermediate casings are inserted into the ...

In this paper, we use the PDE interface of COMSOL Multiphysics® software to implement the 2.5D frequency wave-number domain method to investigate the wave propagation in a deviated borehole penetrating a transversely isotropic formation. A convolutional perfectly matched layer is ... Per saperne di più
斜井和水平井中阵列感应响应特性研究是测井数据正确解释的基础。在斜井和水平井中，井轨迹可能以任意角度进出水平地层，阵列感应测井响应计算是复杂的三维电磁场数值计算。基于 COMSOL Multiphysics® 软件的 AD/DC 模块开发完成斜井和水平井中的阵列感应响应三维数值计算方法。详细计算分析水平井和斜井中井位置、目的层厚、目的层电导率、围岩电导率以及目的层与围岩电导率对比度对阵列感应测井响应的影响。结果表明，水平井的阵列感应测井响应特性取决于层厚、电导率对比度、子阵列间距、仪器距层界面距离等多种因素。当层厚大于仪器分层厚度时，水平井响应与直井响应接近 ...

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... Per saperne di più
Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they ... Per saperne di più
In the study, we present an efficient absorbing boundary domain technique whose main application is the 3D finite element (FE) modelling of the so-called controlled-source electromagnetic (CSEM) data, collected for the geophysical exploration. The developed technique is based on the real ... Per saperne di più
In this paper, a model for numerically obtaining lamb wave modes and dispersion curves in plates is presented. It is shown that COMSOL Multiphysics can be employed to simulate the behavior of guided waves in dispersive plates, which is useful for NDE applications. A two dimensional ... Per saperne di più
A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. ... Per saperne di più
Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosifi ed water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three ... Per saperne di più
