This paper presents an optimized combination of artificial diffusion techniques to stabilize a drift dominated streamer discharge model which includes COMSOL Multiphysics’ Transport of Diluted Species modules for positive ion, negative ion, and electron charge densities, coupled through ... 詳細を見る

This paper presents a numerical study of the deposition of submicron charged spherical particles caused by convection, Brownian and turbulent diffusion in a pipe with a smooth wall and with a cartilaginous ring wall structure (see figure). The model is supposed to describe deposition of ... 詳細を見る

Inductively Coupled Plasma Chemical Vapor Deposition (ICPCVD) has been widely used for carbon-based nanomaterial synthesis because it provides high plasma densities and uniform plasma distribution and allows plasma to be generated in room temperature.[1] During the ICPCVD process, the ... 詳細を見る

Study of neurons plays a key role in the fields of basic and medical research aiming at the development of electrically active implants. The Fitzhugh-Nagumo equations are used to model and simulate the spike generation and propagation in a squid giant axon using COMSOL Multiphysics® 3.5a ... 詳細を見る

Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic ... 詳細を見る

A new design concept for large (6 mm diameter) dynamically focusing silicon membrane mirrors using electrostatic actuation was realized. With this concept membrane buckling by residual compressive stress inside the membrane can be avoided. To eliminate the influence of residual stress ... 詳細を見る

Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... 詳細を見る

A computational method is developed to study probing the electric double layer by Scanning Electrochemical Potential Microscopy. The model is based on a modified Poisson- Boltzmann equation, which takes into account steric effects. We investigated the effect of metallic apex protrusion ... 詳細を見る

Dielectric elastomers are a promising group of smart materials, which finds application within many fields such as soft robotics, wave-energy harvesting, and loud speakers. A dielectric elastomer consists of a thin, stretchable polymer film sandwiched between two compliant electrodes. ... 詳細を見る

Radio Frequency MEMS devices have emerged to overcome the problem of high losses associated with semiconductors at high frequencies. A tunable MEMS capacitor is a micrometre-scale electronic device whose capacitance is controlled through different actuation mechanisms which govern the ... 詳細を見る
