This study presents a model for simulating a subsurface pumped-hydro energy storage (battery) system. The model captures the coupling between fluid flow in an oil and gas type wellbore connected to a large hydraulic fracture embedded in a low-permeability reservoir. By integrating ...

The maintenance plan or rush-to-repair of a subsea pipeline for oil transport may result in the shutdown of the line, in other words, may stop the flow of fluid. During the shutdown, the temperature of the oil tends to decrease continuously, and the heavy molecules tend to crystallize ... Per saperne di più
Surface discharge at the oil-pressboard interface has been classified as the most dangerous fault condition in power transformer because it results in catastrophic failure under normal operating conditions and difficult to be detected. In order to understand the physical features of ... Per saperne di più
Introduction: Polymer materials are increasingly used in machine elements such as seals and plain bearings. In particular, PEEK has gained attention for use in wind turbine applications due to its strength and resistance to harsh operating conditions. However, its low thermal ... Per saperne di più
In this work, a bimetallic strip based thermal sensor was designed using MEMS module of COMSOL Multiphysics® software to monitor the temperature rise in insulating oil which was used as coolant in transformers. The bimetallic strip was designed with different shapes such as cylindrical, ... Per saperne di più
Substances like Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) are suspected to be carcinogenic. Furthermore, MOSH/MOAH migrate through the packaging into food stuff. This work aims at modelling, how much MOSH/MOAH migrates from the packaging into ... Per saperne di più
Oil and water are immiscible fluids and they tend to separate very easily when introduced into a flow stream from two different sources in a flow loop. This model studies the development of mixture volume fraction in an oil-water-flow loop with 3 different passive mixing schemes: (i) ... Per saperne di più
One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. The ... Per saperne di più
本研究成功开发出一种多级梯度结构的OMI纤维膜，其特点包括由外至内纤维直径逐层递减、每层具有双峰纤维直径分布、以及有机-无机复合功能化策略。这种独特结构实现了低压阻下的高效空气过滤，并确保了长期热稳定性。该OMI纤维膜对PM0.3、PM1.0和PM2.5的过滤效率分别达到99.98%、99.99%和100%，且压阻仅为65 Pa。此外，针对压力场和颗粒过滤行为的CFD模拟结果与实验趋势一致。在250 °C热处理12小时后，该OMI纤维膜仍保持94.68%的PM0.3过滤效率和62 Pa的压阻。本研究证明了OMI纳米纤维膜在250 °C下的基础热稳定性与过滤潜力 ...

In this paper we used COMSOL Multiphysics to model basic physico-chemical effects relevant in polymer enhanced oil recovery (EOR) such as non-Newtonian rheology of the displacing phase, permeability reduction, adsorption and salinity effects. COMSOL\'s PDE interface as well as Species ... Per saperne di più
