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 ...

Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, ... Per saperne di più
The flow simulation of solid, particulate materials is still challenging, even though estimations show that three-quarters of products and raw materials are present as granules form in the industry. We can think of grain in the agriculture, raw materials of the glass industry, granulated ... Per saperne di più
Electroporation is a biotechnological technique which subjects cells to strong (~kV/cm), short (~ms) electric field pulses that open pores on the cells’ plasma membranes. Under the appropriate conditions, the pores mediate the passage of exogenous material into cells. If the pores ... Per saperne di più
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 ... Per saperne di più
Stress and failure in the earth have long been observed to couple to hydrogeology. Poroelastic models, introduced by soil scientists, can account for strong two-way coupling between porous crustal rock formations and their pore fluids. Current efforts to provide new energy resources ... Per saperne di più
Fluid injection and withdrawal in deep wells is a basic procedure in mining activities and deep resources exploitation, i.e. oil and gas extraction, geothermal exploitation, geothermal permeability enhancement and waste ?uid disposal. All these activities have the potential to induce ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
Parallelization of microfluidic droplet generators is one of the major challenges that droplet microfluidics has to overcome to contribute significantly towards the sustainable manufacturing of advanced materials such as nanoparticles, quantum dots, active pharmaceuticals, etc. A ...
