A model of a horizontal atmospheric pressure chemical vapor deposition reactor was implemented to aid in the design of a laboratory based one. The model coupled momentum transport, energy transport, and mass transport phenomena to account for reacting fluid flow of a compressible gas in a heated chamber. The system modeled was silicon deposition from trichlorosilane in hydrogen carrier gas.

Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like electroactive polymers (EAPs) or metal oxides. This work investigates the stresses and heat flux of the electrode ...

Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts takes too long, so electrophoresis was used to improve the salt extraction. The objective of this ...

Impedance spectroscopy is a measurement technique that has been investigated in a wide variety of medical applications. An example is the measurement of the dielectric properties of the skin and underlying tissue using sensors placed in contact with human skin with capacitive fringing field electrodes. The aim of this work is to use finite element methods for optimizing the sensor design to ...

In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary conditions were based on the analysis by Rambert et al. who have published the most advanced modeling work in ...

This paper deals with the simulation study using COMSOL on the deformation of drop-within-drop system in a high intensity oscillating electric field. It consists of a composite drop suspended in a continuous phase. This composite drop has a smaller inner drop suspended within the larger outer drop. The outer drop is made up of another immiscible liquid. A high intensity sinusoidally varying axial ...

High level radioactive waste (HLW) generated by nuclear fuel cycle is immobilized using glass melters. In Glass melters such as Joule Heated Ceramic Melter (JHCM) electrodes immersed in the glass generates heat by the joule heating due to electric current passing between electrodes through glass. For melter performance it is required to evlaute temperature distribution in the melter. Thermal ...

To support high frequency transmission, the mammalian middle ear construction is unique. The middle ear bones are connected through two mobile joints, the malleus-incus joint (MIJ) and the incudostapedial joint (ISJ). These synovial joints, consisting of joint capsule and synovial fluid inside, play an important role in sound transmission. We developed our current FE model using COMSOL that ...

The objective of the paper is the assessment of the wind load applied to a real photovoltaic (PV) platform installed on a site situated in Brasov, which belongs to the Transilvania University. The platform has a double-tracking axis mechanism which allows the rotation of the platform disk depending on the sun position, in order to gather the maximum solar yield to produce electricity. The study ...
