Nanoscale zerovalent iron is a promising reagent for the remediation of contaminated groundwater. The aim of the study is to simulate the transport of iron nanoparticles and their interaction with the porous media, their attachment and deposition on the soil grains. The particles ... 詳細を見る

A novel numerical method characterizing groundwater flow in unconfined aquifer is demonstrated. In contrast to the conventional method (Dupuit approach considering horizontal flow only), hydraulic head is simulated in horizontal and vertical directions. The new approach is introduced via ... 詳細を見る

We have simulated the ultrasound-induced acoustophoretic motion of microparticles suspended in an aqueous solution. The full first-order thermoviscous acoustics equations have been implented on a rectangular microfluidic 2D domain excited with an ultrasound field tuned to resonance near ... 詳細を見る

The design of modern electric insulation devices for medium and high voltage (HV) applications requires computational work that goes beyond solving just a Laplace equation for the electric potential, and limiting the electric field below critical values. Both field calculation and ... 詳細を見る

This paper presents a 3D numerical model to predict the whole process of coaxial powder flow, including the particle stream flow in and below the nozzle and also the laser-particle interaction process. The Particle Tracing Module of COMSOL Multiphysics is used to solve the coupled ... 詳細を見る

Patients undergoing surgery are sensitive to infections. The operation staff may spread 10^4 particles per person per minute, of which ten percent are presumed bacteria-carrying. We visualize the influence of the personnel on the air and particle flows for the two most common ventilation ... 詳細を見る

Dilution’s issue during dry machining have raised the interest’s environmental researchers and engineers. In fact, the sampling of dust emitted during dry machining was a serious problem for air quality evaluation at the workplace. Furthermore, the best sampling of fine and ultrafine ... 詳細を見る

HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for ... 詳細を見る

Water-and-energy supply is a global issue of paramount importance. The demand for safe potable water is quickly exceeding the limits of natural regional water resources. Like oil, water is a finite resource; unlike oil, however, water has no alternatives. Water, energy and their ... 詳細を見る

Laminar flow static mixers are accurate, inexpensive fluid mixing devices that can handle a wide range of fluids and mixing proportions. They have a wide range of industrial applications, especially in the consumer product, pharmaceutical, biomedical, and petrochemical industries. A good ... 詳細を見る
