Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... Per saperne di più
Recovery of oil by gas injection is usually inefficient due to the low viscosity of the gas, which results in bypassing of the oil. By adding surfactant solutions it is possible to get in-situ foam formation. Foam has a much higher “viscosity” and hence does not bypass the oil, leading ... Per saperne di più
In general, macroscopic two-phase flow in porous media is a mixture of connected and disconnected oil flow. The latter is expressed as ganglion dynamics and drop traffic flow, patterns observed experimentally in pore network models [1,2] and real porous media [3,4]. This characteristic ...

Lubricant oil is used to ensure proper functioning of industrial machinery such as turbines, gears, bearings and compressors. Oil analysis is used to detect and quantify the presence of wear metals and other contaminants in the lubricant of oil wetted systems, by sensing the change in ... Per saperne di più
Oil production industry investigates new methods to improve oil extraction from natural rocks. Since long time the dedicated simulation software has been used to better understand the behaviour and predict the production from oil reservoirs depending on the developed technologies. Modern ...

One of the upcoming technologies in displays is that of the electrowetting displays. A surface can be covered by a colored oil or transparent water using a voltage to increase or decrease the wettability of the surface. A simulation of the behavior of such a thin film of oil in water, ... Per saperne di più
Energy loss from fluids flowing across long distances presents a problem in many applications. In the oil and gas industry, for example, crude oil can change in viscosity when modest changes in temperature are realized. This can lead to added pumping power requirement and thus more heat ...

Electromagnetic (EM) flowmeters are important flow sensing devices across industries like oil and gas and power generation. The EM flowmeter works on the principle of Faraday’s law of electromagnetic induction. In short, when an ionic fluid like water flows through a pipe, in the ... Per saperne di più
Digital rock physics (DRP) is an emerging field where a rock sample is imaged, relevant physical processes are simulated numerically on the digital rock sample, and the numerical solutions are used for understanding and interpreting the rock in different in-situ conditions. The use of ... Per saperne di più
In fractured reservoirs, much of the oil is stored in low permeable matrix blocks that are surrounded by a high permeability fracture network. Therefore, production from fractured reservoir depends on the transfer between fracture and matrix, which is critically dependent on their ... Per saperne di più
