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
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
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
Today, low noise is a mandatory feature for power transformers to comply with customer specifications and environmental regulations. Therefore, it is crucial to develop sound prediction tools with sufficient accuracy to avoid overkill margins in design and costly modifications after ... Mehr lesen
Reynolds Numbers effect: In the first bend, the higher the Reynolds number, the longer the first pair of vorticities stays attached to the wall. In the second bend, the higher Reynolds Numbers, the secondary flow from the first bend dominates. Curvature Radius effect: The smaller the ... Mehr lesen
THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and ... Mehr lesen
The evaluation of defect size and nature are two most controversial topics in ultrasonic flaw detection. The operation consists of an application of ultrasonic waves to pipes in order to detect metal loss and other defects in the pipe wall due to corrosion and other degradation ... Mehr lesen
Introduction Micro-Spherically Focused Logging (MSFL) tool is a microresistivity open-hole logging tool designed to measure the resistivity of the flushed zone, a region of formation close to the borehole, independent of any mudcake on the borehole wall. Original designs of MSFL were ... Mehr lesen
In inductive heating simulations the electromagnetic properties of the steel have a significant impact on the temperature pattern along the heated product. Indeed, taking into account the non-linearity of the ferromagnetic material properties is a key point to have relevant simulation ... 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
