Surface acoustic wave gas sensors use a chemically sensitive resistive layer to detect gas concentration. The resistivity of the sensing material, the sensing layer thickness, and the spacer layer thickness all affect the surface wave propagation velocity. Existing analytic theory ... Per saperne di più
This paper presents the quasi-TEM two-dimensional (2D) approach for the analysis of multiconductor transmission lines interconnect in single and two-layered dielectric region using the finite element method (FEM). FEM is especially suitable and effective for the computation of ... Per saperne di più
This document describes a method for maintaining the long-term calibration of a full color direct thermal printer. An essential component of the system is a thermal model created using COMSOL Multiphysics that allows fitting of color data recorded at different temperatures and exposure ... Per saperne di più
A reaction between chemical species is modeled by a particular reaction pathway, in which one reaction is very fast relative to the other one. The diffusion controlled reactions of these species together with a reaction intermediate are described by a system of three transient reaction ... Per saperne di più
A kernel of grain is modeled as an isothermal sphere, with descriptive differential equations scaled or rendered into non-dimensional form, where moisture transfer is governed by internal diffusivity, not by surface conditions. The time dependent problem is solved with COMSOL and the ... Per saperne di più
In this paper we present a study of the time dependent analysis of a metal hydride bed (MHB) which provides constant flow to a fuel cell at required power loading and pressure. The hydrogen gas phase pressure, the hydrogen concentration in the metal hydride and the hydrogen desorption ... Per saperne di più
Corrosion of rebar in concrete is one of the most prominent durability problems in reinforced concrete, especially where de-icing or seawater salts come into contact with the structures. Previous electrochemical and microscopic investigations have shown that local crevices between the ... Per saperne di più
Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous ... Per saperne di più
Parametric finite element simulations were performed to study the effect of film thickness, and electrode size on the different impedance parameters for insulating thin films deposited on a conductive substrate. COMSOL Multiphysics® was used to solve the quasi-static form of Maxwell’s ... Per saperne di più
This paper presents the solution of a transient electromagnetic problem using COMSOL Multiphysics. The paper also presents a closed-form solution of a transient electromagnetic dipole. The computational solution compares well with a closed-form solution for this problem. This work ... Per saperne di più
