Viscoelastic Mechanical Analysis for High Temperature Process of a Soda-Lime Glass Using COMSOL Multiphysics
Material and Production Engineering Department, University of Naples “Federico II”, Naples, Italy
Glasses are widely used in the modern industry. For high temperature the glass behaves very much like a Newtonian liquid with temperature-dependent viscosity. The goal of this study is to set a numerical procedure in order to study the glass forming process of soda-lime glasses used in the automotive field by means numerical simulations.

Photovoltaic systems can degrade with moisture. The addition of an edge-seal containing a desiccant can reduce the amount of water reaching the interior. This report discusses the modeling of the water transport into the system to determine the amount of edge seal and desiccant required. The moving freezing front of the Stefan heat-transport problem is used to model a moving moisture ...

A key issue for the development of a LENR power unit involves the measurement and energy output of the reaction. Our team is currently studying a gas loaded nanoparticle-type cluster power unit  which pressurizes various nanoparticle alloys with either deuterium or hydrogen. The principal elements in the various nanoparticle alloys are Nickel, Palladium and Zirconium, with each alloy ...

Multiphysics Simulation of Polymer-Based Filters for Sub-Millimeter Space Optics This work focuses its analysis on polymer-based filters used in space-borne astronomical instrumentation for Cosmic Microwave Background Radiation and Far-Infrared observations. Most of these observatories mount quasi-optical elements made of such materials, due to their high transparency and low absorption in ...

Schistosoma mansoni parasites affect million people worldwide. The intensity of the infection can be evaluated by the number of eggs present in the stool of an infected individual. The application of the traditional methods has been regarded as impractical in developing areas and there is a continuous search for new techniques. In face of this scenario, a new method of diagnosis was explored in ...

The objective of this paper is to design and simulate Carbon Nano-Tube (CNT) based mass sensor that determines extremely low measures of molecules using COMSOL Multiphysics® software. The ultimate goal of this nanomechanical resonator sensor is that it allows detection at single molecular level. The change in the mass from the resonator can cause a shift in the resonant frequency. The ...

The XENON Dark Matter Experiment utilizes ultra-pure xenon (Xe) as a target for particle interaction in the effort to detect dark matter particles. To measure the purity of Xe, a gas purity monitor (GPM) is being developed which drifts electrons through Xe gas to detect impurities that contribute to charge attenuation. An axially-symmetric model is used to simulate the electric field generated ...

Giant vesicles (GVs) are artificial chemical systems largely used as cell models, since they are micrometer-sized closed compartments bounded by a semi-permeable membrane, which in turn is composed by self-assembling amphiphiles. By opportunely engineering the lipid membrane and by entrapping cascade-reaction enzymes inside GVs, it is possible to design micro-sized reactors where metabolic ...

In climates with high temperature and solar radiation, reducing the cooling consumption and increasing the standards of indoor comfort are topics of great importance. The roof plays a key role in controlling the indoor thermal comfort. In ventilated roofs, air flow within the ASV (Above Sheathing Ventilation) depends on the air entering and leaving at the eaves and the ridge, according to ...

One challenge with converting nuclear research reactors to low enrichment fuels is the thermal-fluid performance. Local areas of high temperature, known as hotspots, limit reactor performance and thus require accurate modeling. A simplified fuel plate model is eveloped to compare traditional FEA techniques with the thin layer and thermal contact features in the COMSOL Multiphysics® software for ...
