Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... Mehr lesen
The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... Mehr lesen
Darcian and non-Darcian porous media are characterized by the porosity of medium. To capture miscible viscous fingering in both types of porous media, a new model built with COMSOL® software is presented by coupling of two different physics interfaces (hydrodynamics and transport of ... Mehr lesen
Preparative chromatography is an important separation method where the simulated moving bed (SMB) technology is an increasingly used separation process for binary mixtures. Several chromatographic columns are arranged in a ring where the feedings and drains are changed cyclically to ... Mehr lesen
The primary motivation of this work was to develop flow models in porous media with fractal properties to represent the anomalous behavior observed in some pressure tests in naturally fractured reservoirs. Mehr lesen
In this paper, the mechanism of charging process was simulated and analyzed. The simulation was conducted using COMSOL Multiphysics® software, based on the laminar two-phase flow level-set interface coupling with the electrostatic interface. Meanwhile, different parameters (such as the ... Mehr lesen
The CROWN project is a collaboration between 8 partners (LIC Energy, TWI, EDF Energy, DONG Energy, ORE Catapult, Wilton Engineering, Universal Coating, Metallisation) that is born from the offshore wind (OW) industry interest in the potential of Thermally Sprayed Aluminium (TSA) as ... Mehr lesen
Thermoelectric materials have no theoretical limit to conversion efficiency of heat into electrical power. In order to compete with other forms of power generation and small-scale energy conversion, thermoelectric converters need to maximize their practical usability when integrated with ... Mehr lesen
Teledyne Marine developed a system for the long-range ocean acoustic tomography, which uses a tunable, high-efficiency sound resonator. The high-Q resonator tunes to match the frequency and phase of a reference frequency-modulated signal. The analysis of a high-Q resonant organ pipe with ... Mehr lesen
海上石油泄漏不仅造成资源的浪费，还长期威胁着脆弱的生态系统。然而浮油具有面积大、油层薄、粘度大的特点，难以采用传统的技术和材料来有效地处理。作者利用石墨烯海绵疏水亲油、导电的特点，设计了一种原位加热的方法，有效地较低了原油的粘度，增大了油在海棉里的扩散系数，在解决快速吸附高粘度原油这一世界性难题方面取得了突破性进展。 在这个研究工作中，作者发现很难在实验上获得此方法的能量消耗情况，为了回答这个问题，作者应用 COMSOL® 软件，模拟了石墨烯海绵加热吸油的热传导过程。运用电流模块，模拟石墨烯泡沫通电加热升温的过程，用热传导模块模拟热量通过石墨烯泡沫传递到油、水 ... Mehr lesen
