In this paper, the Robust Design of a Linear Electric Motor (LEM) is performed. A Robust Design is a set of nominal parameters that satisfies the customer constraints with uncertain parameters. In particular, it is possible to obtain the Most Robust Stationary Design (MRSD) of a Performance Function (PF) by looking at the minimum range of the Interval Extension of its Taylor series. Furthermore, ...

The paper presents the modeling and simulation of 2D heat and moisture transport with and without air movement for a building construction. The research focuses on the effect of air movement through building constructions. Although the typical air movement inside building constructions is quite small (velocity is of order ~10-5 m/s), this research shows it might have much more impact on the ...

We model the liquid transport in foam (i.e. drainage) by unidirectional flow transverse to a triangular planar area that represents channel (i.e. Plateau borders) cross-sections. Partial mobility of the interfaces is obtained balancing the bulk viscous stress with the surface viscous stress and a velocity equal to zero is imposed at the vertices. In liquid foams, the wedges of the channels are ...

This note addresses the concept of wave energy conversion by means of a piezoelectric material. The ocean surface waves represent an important source of energy. A multiphysics simulation is used to focus on different aspects, namely the free surface wave, the fluid-structure interaction, the mechanical energy input to the piezoelectric material and the electric power output, using an equivalent ...

In Electrical Impedance Tomography (EIT), an array of surface electrodes is used to inject current and measure the resulting voltages to non-invasively obtain conductivity distributions of objects. The system can be easily implemented as a device that monitors hemorrhage, respiration, gastric emptying or brain activities.The Quantity Index (QI), an integral measure of reconstructed images, can be ...

An eigenvalue as well as a harmonic response analysis is performed on the Gullfaks C, Knock Out Drum (KOD) including some of the connecting pipe systems. The vibration behavior of two new choke valves and their specific connection to the KOD are of special interest. The main concern is the low frequency induced vibration as a consequence of the platform movements. A frequency band between 0-20 Hz ...

The development of atherosclerosis leads to the formation of an atheroma plaque which takes place in the artery. This plaque is composed of two parts: a lipid deposit and a fibrous cap. The fibrous cap covers the lipid deposit and isolates it from the blood flow. The blood flow that circulates in the artery modifies the geometry of the atheroma plaque and can cause dangerous effects, such as a ...

The steady-state non-equilibrium distributions of two species of mono-valent ions around a charged nanofluidic channel have been examined. Large reservoirs were placed on either side of the nanoscale channel to simulate bulk concentration of ions in a fluid. Results from COMSOL Multiphysics simulations show that the effect of the potential bias across the nanochannel yields a significant ...

This paper intends to show a model of a monolithic reactor for the autothermal reforming process (ATR), a process that uses hydrocarbons to produce H2. The ATR chemical reactions take place on the surface of monolith channels coated with a catalyst. The isothermal ATR reactor is modeled using 42 catalytic surface chemical reactions that involve 13 solid species and 7 gas species. To solve the ...
