This paper presents preliminary estimations of CO2 overpressure into the reservoir and CO2 leakage through the caprock and the overburden. A simple, two-phase flow model in porous media based on Darcy’s law was used, in order to explore easily long time periods. The models produced by COMSOL Multiphysics allow sensitivity studies and preliminary evaluations of the relations between CO2 leakage ...

A fundamental understanding of the transport phenomena in microfluidic channels is critical for systematic design and precise control of such miniaturized devices towards the integration and automation of Lab-on- a-chip devices. Electroosmotic flow is widely used to transport and mix fluids in microfluidic systems. Electroosmotic transport in convergent divergent micronozzle is significant in ...

High intensity discharge lamps can experience flickering and even destruction, when operated at high frequency alternating current. The cause of these problems has been identified as acoustic resonances inside the lamp’s are tube. Here, a finite element approach for the calculation of the acoustic response function is described. The developed model does not include the plasma dynamics.

Heat conduction through a slab, 0 ≤ x ≤ W is one dimensional. However, if one of the edges, say x=0, is rough the conduction will be two dimensional. The two dimensionality varies with the correlation length with a maximum at a length approximately 10% of the slab width. The maximum percentage standard deviation of the flux is of the order of 3 time that of the roughness. Monte ...

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 electromagnetic fields in strongly inhomogeneous media. We illustrate that FEM is as suitable and effective as other ...

We present COMSOL-based analyses and design optimizations of a micromachined wind sensor. The sensor relies on eight germanium thermistors embedded in a thin silicon nitride membrane, where two orthogonally arranged ensembles, each consisting of four thermistors, are connected to form a double Wheatstone-bridge. In operation, each bridge is supplied by a constant current and the self-heating of ...

Using modeling software such as COMSOL Multiphysics during the design phase, an approach called “simulation-led design”, allows ideas to be both inspired and validated by the use of simulations. Then, using simulations after the product is designed can shorten the prototype-testing portion of the development process and reduce its cost. This paper provides specifics on the nature of the ...

Introduction of silicone hydrogel contact lens materials provided products of unprecedented capability to deliver oxygen to the eye during wear. One additional material characteristic of interest is the material’s permeability to ions. This paper discusses descriptive tools and optimization of an impedance method of characterizing ion permeability. A physical model of conductive paper with ...

Spacecrafts have a prime necessity that their temperature be controlled. This paper presents the simulation of a mechanically actuated field effect transistor that is used in a thermal system. It comprises of a composite beam, a piezoelectric substrate and a field effect transistor. The temperature rise causes a deflection in the composite beam thereby causing it to impinge on the piezoelectric ...
