During the welding of tantalum with a ND: YAG pulsed laser, a deep and narrow cavity, called the keyhole, is formed. At the end of the process, surface tension forces provoke the collapse of the keyhole. For important interface deformations, gas bubbles can be trapped into the melting ... Read More
The microwave heating and processing of heterogeneous material is usually simulated using a set of coupled PDE equations in an homogeneous medium. Nowadays it is possible to describe more accurately the process with a suitable description of the heterogeneities that is at the grain ... Read More
Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of ... Read More
One of the upcoming technologies in displays is that of the electrowetting displays. A surface can be covered by a colored oil or transparent water using a voltage to increase or decrease the wettability of the surface. A simulation of the behavior of such a thin film of oil in water, ... Read More
Variable capacitors between the fF and pF range are very interesting for high frequency applications like variable filters, resonators, etc. For radio astronomy applications variable capacitors, realized by electrostatically actuated, micromechanical Meanders-suspended bridges (MEMS) ... Read More
Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a ... Read More
Drug therapy of the posterior part of an eye is very challenging. Yet, in USA alone, there are almost 2 million people affected by age related macular degeneration. When designing a strategy for controlled-release drug delivery, it is important to take into account of physiology, ... Read More
Second-generation high-temperature superconducting (HTS) tapes are very promising superconductors for ac applications and numerical models are very important for predicting their performance, e.g. for computing the ac losses. These tapes are characterized by a very large aspect ratio: ... Read More
In recent years, a number of numerical and finite-element-methods in particular - some implemented in COMSOL - have been developed to investigate various properties of superconducting materials. Following converse conclusions by different models regarding similar physical phenomena, the ... Read More
Given any equation L(u)=0, e.g. a partial differential equation, it can be considered to be the stationary solution of a time dependent equation (in fact, time need only to be fictitious time not real time). Our approach is to choose the time dependence in analogy with an oscillating ... Read More
