In this work, COMSOL Multiphysics was used to develop a model to investigate the degree of saturation in sloped terrain. The model was validated via laboratory experiments incorporating Lan’s man-made rainfall slope model test. The validated model was used in an actual case study to simulate the Maokong Landslide.

This work deals with the modeling and the numerical simulation of the CO2 absorption, coupled with a chemical reaction, in an initially quiescent aqueous solution of sodium carbonate (Na2CO3) and bicarbonate (NaHCO3), inside a Hele-Shaw cell. In our Hele-Shaw cell, the liquid fills partially the gap between two parallel transparent Plexiglas plates. CO2 is forced to flow above the liquid in the ...

Ohmic heating is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This is particularly useful for very thick fluids, those that burn on to hot surfaces and those with high solids content which would cause difficulties for conventional heating techniques. Processing of animal by-products (ABP) faces all these ...
Calculation in Coupling Coefficient of 1.3μm Quantum Dots Distributed Feed Back Laser with Half Etched Mesa Structure

Quantum Dots (QDs) laser is expected to have a low threshold current density and high thermal stability. We propose the QDs laser with the half-etched mesa distributed feedback (HEM DFB) structure. We accurately calculated the coupling coefficient in a HEM waveguide using the finite element method (FEM).

Introduction: Flexures are low-cost bearings that are capable of providing motion guidance with high repeatability and low friction (Figure 1). However, applications of flexure bearings are often limited by their low range. This is because motion guidance in flexures is provided by bending/flexing of members; thus, range is limited by the bending stiffness. As the bending stiffness can be ...

In this study, COMSOL Multiphysics® software was applied to the investigation of the electromagnetic behavior of an optical crystal submitted to the magnetic field generated by electric current in a near positioned metallic conductor. Moreover, the influence of a ferromagnetic apparatus (magnetic concentrator) on the magnetic field acting upon the crystal was investigated. Three cases were ...

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of the bricks, in particular the predicted time at which brick shrinkage reverses into expansion, generating large ...

Modern aluminum casement windows consist of an inner and outer profile made of aluminum, which are separated by an insulating bar made of polyamide (see Figure 1). Due to the low heat conductivity of the plastic material the thermal interaction between the living space and the surrounding is reduced significantly, but thermal expansion of the different materials could cause elastic or even ...

During the basic operation of a lithium-sulfur (Li-S) cell, sulfur molecules are required to undergo a complex mix of electrochemical and chemical reaction processes. To date, almost all modeling of Li-S cell behavior has been undertaken using electroneutral, structurally homogenized, cell scale models accounting for most of these processes. The presented work was undertaken in order to try and ...

Carbon fiber as filaments or as continuously reinforced composite finds application in the electronic packages, electric vehicles, and electrical machines, owing to its excellent electromagnetic (EMI) shielding and high conductivity. Carbon fiber being good conductor of electricity (in the order of 105 S/m), and the binding resin is insulating material (10-13 S/m), the response is non-linear and ...
