A ball is in contact with a plane, and a lubricant separates the two surfaces to decrease friction during their relative motion. To avoid wear, the lubricant film thickness should be higher than the surface roughness. The goal of this paper is to show how it is possible to solve ... 詳細を見る

In this work the solution of the structural problem obtained by mean of the velocity approach is presented. More in detail the balance and constitutive equations are expressed in Eulerian form, the mesh is not material. The approach is general, is suitable both for material boundary or ... 詳細を見る

Numerical homogenization is based on the use of finite elements for the description of average properties of materials with heterogeneous microstructure and composites. The Representative Volume Element (RVE) of a masonry is solved with COMSOL Multiphysics®. It consists of linearly ... 詳細を見る

To understand origins and consequences of drying phenomenon during composting, a compositional drying model of a partially water-saturated porous media coupled with biodegradation has been developed. The different simulations carried out under COMSOL Multiphysics demonstrate the ability ... 詳細を見る

The Helmholtz Coil generates a uniform magnetic field. The commercially available large-size Helmholtz coils prove to be very expensive. This paper describes the economical method of designing and construction of a Helmholtz coil. COMSOL Multiphysics AC/DC Module simulated results and ... 詳細を見る

Using modeling software such as COMSOL Multiphysics during the design phase, an approach called “simulation-led design”, allows ideas to be both inspired and validated by the use of simulations. Then, using simulations after the product is designed can shorten the prototype-testing ... 詳細を見る

This paper deal of the forming process applied to the thermoplastic composites. A new thermoforming process that uses rubber particles collection as flexible mould was presented and numerically modeled. A characterization of the rubber in particles form was previously performed to value ... 詳細を見る

Pressure-driven air flow is directed over the microfluidic cavity induces circulating fluid motion in the cavity. Analyte contained in the air stream is absorbed into the cavity, mixes with the nanoparticles as a result of the circulating cavity flow. Therefore, the nanoparticles ... 詳細を見る

Cu-Nb multilayer nanocomposite has prospective applications in nuclear industry because of its ability to self-heal from radiation damage. The goal of the study is to find a suitable joining method for the composite to produce industrial-scale pieces, free of defects threatening the ... 詳細を見る

This contribution is devoted to the mathematical modeling of the AC electroosmotic micropumps in COMSOL Multiphysics and Matlab. The mathematical model involves the microchannel surroundings and several AC-voltage driving modes. The weak form has been used for handling singularities and ... 詳細を見る
