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.

There are two types of vertical axis wind turbine, drag-type and lift-type. Drag type wind turbine can rotate in low speed wind condition, although its rotation speed is low. Lift type wind turbine can rotate at higher speed, although it works only in high speed wind condition. This study investigates new blade profile that realize rotation in low wind speed condition and higher rotation speed ...

As it is known nano-sized emitters (such as atoms, quantum dots and point defects in diamonds) interaction with nano-environment leads to drastic changes of their decay rate and therefore lifetime (Purcell effect). To calculate the influence in general one needs to solve equations of quantum electrodynamics. However in weak interaction limit these emitters can be considered as point electric ...

Marine Vibrators are a coherent type of sound source, which can be quieter and less harmful for marine habitants than traditional air-gun technology. Such source gives clearer, more precise and higher resolution imaging of the bottom properties due to the coherent signal and streamer array processing. Teledyne Marine Systems is developing a coherent seismic marine sound source technology ...

This abstract introduces a sensor design for detecting angular acceleration in a single plane using thermal convection. The working principal of the device is based on probing temperature profile changes along a micro-torus caused by angular acceleration. By properly choosing the locations of the heaters as well as the temperature sensors, the output signal will correlate to in-plane angular ...

An ion trap resonator, used for mass spectrometry, is investigated. Simulations are used to define the stabilization criterion of ion trajectories by optimization of the electrode configurations. The ion interactions are investigated and shown to help in reduction of ion-diffusion. Space charge effects simulate the induced voltages on pickup electrodes.

Este trabalho trata do dimensionamento da estrutura bocal/difusor utilizando a simulação computacional com fronteira móvel. Esse tipo de simulação contempla toda estrutura da bomba, isto é, câmara de bombeamento, difusor e área de dispersão de fluxo, de modo a contabilizar o refluxo em função da estrutura, possibilitando um projeto mais realísticos da estrutura.

A biotransformação de substratos utilizando enzimas imobilizadas em nanopartículas presentes num meio fluido (substrato), contido num bioreator CSTR, foi investigada. O software COMSOL Multiphysics foi usado para simular o sistema através do uso das equações de difusão de espécies apropriadas para o consumo do substrato. Nessa investigação, a difusão na superfície da nanopartícula, onde ocorre a ...

The present work investigates the role of suspended liquid-gas interfaces for applications involving the reduction in flow resistance using the COMSOL multiphysics software. A pressure-driven viscous flow of a liquid through microtubes containing superhydrophobic surfaces patterned with alternating micro-grooves and ribs has been considered. Employing a 3D simulation, a fully-developed laminar ...

As the light output of the LED is strongly dependent on the thermal performance, thermal interface material (TIM) has become an area of interest that can be used to sink more heat out to the ambient. In COMSOL Multiphysics, physics interfaces like joule heating, heat transfer in solid and laminar flow are used to simulate the thermal dissipation with the specific material properties and ...
