Laser-induced forward transfer (LIFT) is a non-contact direct-write technique that enables the deposition of small volumes of material into user-defined high-resolution patterns with a wide range of structural and functional materials. There are many variations of the LIFT process, each ... Mehr lesen
The Finite Element Method (FEM) has become an established numerical tool used for different academic and industrial purposes. It allows the prediction of weld pool geometry, thermal cycle, final distortion and residual stress field during and after fusion welding. The capability of the ... Mehr lesen
This work investigates the ablation of a copper surface caused by the irradiation of a 220 ns laser pulse. Our focus is on the heat transport within the copper and takes the proceeding vaporization of surface substance into account. Our model ignores plasma dynamics and simulates the ... Mehr lesen
INTRODUCTION The purpose of this work is to verify the effect of Multigrid method on the CPU time for the resolution of the heat transfer model, based on the Finite Element Method (FEM), in order to simulate the laser surface remelting (LSR) of the Al–1.5 wt.% Fe alloy. To accelerate the ... Mehr lesen
Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... Mehr lesen
A 3D thermo-mechanical simulation was developed using COMSOL Multiphysics software in order to predict distortion of a welded dissimilar titanium alloys structure. An angular distortion and a longitudinal shrinkage are predicted in agreement with those obtained experimentally. Mehr lesen
We present the design and performance simulations for a microwave cavity for use in novel compact cold atom atomic clocks. Design goals for such a microwave cavity are a resonance frequency at the Rubidium ground-state transition frequency of 6.835 GHz, combined with a moderate quality ... Mehr lesen
Laser immunotherapy (LIT) was developed to treat late-stage, metastatic cancers through local laser irradiation and immunological stimulation. In ILIT, the photothermal effect induces immune responses by destroying and interrupting tumor cells through temperature elevation in target ... Mehr lesen
The main purpose of this paper is to develop a proof of concept software that can simulate the geometry of engraved surfaces and can estimate the depth and width of engraved groove and associated laser parameters. For this purpose, COMSOL has been used to simulate the moving laser beam ... Mehr lesen
In all implantable medical devices, one main challenge is to assure no water penetrates in the electronic part of the system. To be able to transmit the electronic information from the inside of the device to the lead without any water infiltration, we used a complex part called feed ... Mehr lesen
