A shift-and-weight method for fast interpolation of probe charge electrostatic potentials

C. Roman1, N. Spiegelhalter1, C. Hierold1
1ETH Zurich, Switzerland

The Poisson equation, as implemented in the COMSOL Multiphysics® AC/DC module, solves for the electrostatic potential due to general charge distributions subject to various boundary conditions, very often Dirichlet conditions of constant potential at conductor surfaces. When both the ... Saiba Mais

Calibration of thermal model to simulate laser assisted bonding process

G. Spinola Durante1, R. Jose James1, E. Rutz Innerhofer1, K. Krasnopolski1
1CSEM, Switzerland

In this poster we present the results of the strategy for calibrating the COMSOL Multiphysics® model to simulate the laser bonding process (LADB) of Mems chips. A specific aspect of this work is to calibrate the COMSOL Multiphysics® heat model loss by measuring with a miniature ... Saiba Mais

Concept Level Automotive Structural Analysis in COMSOL Multiphysics®

Mihir Bhalerao1, Alok Thanapati1, Chandrakant Deshmukh1, T. K. Hareesh1
1Mahindra and Mahindra Ltd., Chennai, Tamil Nadu, India

At the start of any automotive project, preliminary concept structures are generated which need to be analyzed in a fast and efficient manner. Concepts of different structural elements such as the chassis frame, cargo, Cross Car Beam etc. need to be optimized and front-loaded with ... Saiba Mais

THERMO-ELASTIC STUDY OF A SPACE ACTUATOR BALL BEARING SET

Zain Mansoor1, Claudia Allegranza1
1ESA/ESTEC, Keplerlaan 1, 2200 AG, Noordwijk, Netherlands

Ball bearings are used in vast majority of mechanisms for space applications (such as Solar Array Drive Mechanisms, pointing mechanisms or reaction wheels) in order to provide low friction and smooth motion between parts. These applications differ from the ground ones due to space ... Saiba Mais

Numerical Modelling and Validation of Induction Melting of IN713C for Investment Casting

V U Thomas1, M A Yar1, S Mehraban1, J C T Cullen1, S G R Brown1, N P Lavery1
1Swansea University, UK

Investment casting is practised in both the automotive and aerospace industries, to produce casted components where a high-quality surface finish is critical. Vacuum induction melting (VIM) and direct pouring into an investment casting shell mould is an advantageous manufacturing ... Saiba Mais

In-Situ Scale Inhibitor Interaction with Surface Area of Porous Sandpack: A Numerical Approach.

Uche C. Anyanwu1
1Department of Engineering, Robert Gordon University, Aberdeen, AB10 7GJ, Scotland, UK

ABSTRACT: Over the years, the most common method of preventing scale formation and blockage of formation pores in oil and gas systems is by squeezing of chemicals into the formation. Different experimental and simulation studies have been carried out to understand the interaction of the ... Saiba Mais

FE-Simulation of PTCA Balloon Catheters

Cornelia Amstutz1, Roman Bühler1, Jean-Marc Behr2, Michael Stöver2, Adrian Zurbuchen1, Jürgen Burger2
1SITEM Center, University of Bern, Switzerland
2SIS Medical AG, Switzerland

Within 40 years, percutaneous transluminal coronary angioplasty (PTCA) catheters evolved into the golden standard for treating coronary stenoses. However, navigating through tortuous vessel pathways and cracking highly calcified lesions is challenging. To minimize the risk of ... Saiba Mais

Simulation of Nonlinear Optical Absorption in Silicon Optical Waveguide

Yaohui Chen1
1Nvidia, Ledreborg Alle 130B, 4000, Roskilde, Denmark

From the perspective of nonlinear silicon photonics, the strong light confinement in sub-micron sized silicon waveguides increases the effective nonlinearity. However, the high optical power density in the waveguide core also increase nonlinear absorption and hence the device self ... Saiba Mais

Acoustic manipulation capabilities of a multifrequency AlN based PMUT

Bart Weekers1
1Imec / KU Leuven, Leuven, Belgium

Contactless manipulation of microscopic objects through acoustic waves has proven an attractive solution for several applications over the past decades. This modality is particularly interesting for the manipulation of bio-particles (BPs) due to its relatively low intensities, capability ... Saiba Mais

Investigation of environmental variations on the performance of a cascade impactor

Dara Bayat1, Maxime Auchlin1, Olha Sereda1, Mohammad Mehdi DADRAS 1
1CSEM SA, Switzerland

The goal of this study was to simulate the collection efficiency curves of a Dekati-ELPI® cascade impactor. Seven of the twelve stages of the device in the lower range of deposition, D50 of 10 nm to 600nm, were simulated. “High Mach number flow; laminar & turbulent” and “particle ... Saiba Mais
