Cold season thunderstorms are a threat for wind turbines in several areas of the world because the thundercloud is much closer to the earth compared to warm season thunderstorms. As a consequence, the electric field between cloud and ground is much higher during these storms, triggering ... 詳細を見る

HVDC electrodes are installed on HVDC transmission systems to provide a low resistance current return path during both monopolar and bipolar operation, using the earth and/or sea as the conductive medium. HVDC electrodes are in general less costly and have lower losses than dedicated ... 詳細を見る

This study investigates the effect of a uniform magnetic field on the lateral migration behavior of a ferrofluid droplet in a plane Poiseuille flow at arbitrary directions by means of numerical simulation. A numerical scheme called level set method in combination with the laminar two ... 詳細を見る

We present a detailed 2D COMSOL Multiphysics® model used to determine and improve the conversion efficiency in a liquid-metal microfluidics-based portable energy transducer. To date, most work on power generation technologies has focused on the optimization of existing technologies, and ... 詳細を見る

The dynamics of phase slip centers in a 1D model of superconducting wire was created based on the set of time-dependent Ginzburg-Landau equations (TDGL). The General Form PDE interface of COMSOL Multiphysics® simulation software was used. TDGL has successfully applied to this problem ... 詳細を見る

An important attribute for numerical simulations is to provide accurate quantified solution values. Thus it is useful to find complex problems with analytic solutions to confirm the numerical results obtained from software. The well-known proximity effect causes a redistribution of ... 詳細を見る

Power Transformers are the most important piece of power system elements and protecting this device from failures, especially from the internal faults has been a major challenge. The internal faults such as Turn-to-Turn (T2T) and Turn-to-Ground (T2G) has been attributed to most of the ... 詳細を見る

Photothermal deflection spectroscopy (PDS) relies on the angular displacement of a probe beam through a fluid with varying index of refraction. The precise angular displacement of the probe beam is dependent on the entire index of refraction field, which is in turn dependent on fluid ... 詳細を見る

CT and MRI are current techniques used for stroke detection. Although they are favored for their high accuracy and resolution, there are many situations that a potable and low-cost imaging technique is required. Ultra-sound technique is portable, but it cannot be used for stroke ... 詳細を見る

At the moment of DC activation, charged surfaces begin interacting with the adjoining electrolyte solution. The charges along the surface of that interface slowly attract oppositely charged ionic particles, which eventually gather on or near the surface, creating the Electric Double ... 詳細を見る
