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 ...

Understanding the interactions between microbubbles and surfaces is key to the successful deployment of microbubbles in a range of applications. Two important examples are their use as a drug delivery mechanism, and their potential use of acoustically-driven bubbles as microscale sensors. Drug delivery with bubbles involves sonication at high frequency close to a boundary, and sensing with ...

The approach of this project is Modeling a Coriolis Mass Flow-meter (CMF) bases on a Fluid-Structure Interaction (FSI) device. The "Coriolis mass flow-meter sensor" is modeled using COMSOL Multiphisics® simulation, the Acoustic-Shell Interaction physics interface and coupled by FSI physics interface to drive and simulate the sensor. The modeling and simulation are provided into two different ...

Introduction: This study aims the optimization and sensitivity analysis of an existing device. A Secondary Ion Mass Spectrometer (SIMS) device is to be equipped with a high power laser in order to increase sputtering speed. The modified device must be capable of handling the increased level of contamination and energy spread of sample ions. Use of COMSOL Multiphysics® software: Transmission ...

Magnetic levitation systems have been studied in the context of high-speed transportation as maglev trains, high speed machinery as magnetic bearings, and other similar engineering applications. In this paper, a three dimensional arbitrary shaped object is modeled and analyzed through COMSOL. Mechanically the levitated object has three degrees of freedom- two along the x and y axes and the ...

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to induced eddy currents as a result of sodium flow. It consists of a central primary winding, energized from an A.C. ...

A quasi static indentation test on a laminate composite has been investigated numerically and experimentally. In particular, the test has been implemented by COMSOL Multiphysics® and optimizing the Finite Element and mesh. In addition, the numerical strain results have been validated by the comparison with the respective experimental deformation data that have been obtained by fiber Bragg ...

Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as well. Electromagnetic and acoustic or seismic techniques may provide the significant advantage of a mobile non ...

Electrorefining is an electrolytic process for obtaining high purity metal. In this process the impure metal is made anode and the high purity metal is deposited on cathode. Electrorefining is a key step in pyrochemical reprocessing of spent fuel from metal fuel fast reactors. Development of an electrorefining cell, in which processing of 10 kg of simulated spent fuel will be demonstrated, is ...
