Optimization of Loudspeakers
Loudspeakers, specifically electrodynamic transducers with enclosures, are used almost everywhere in our life. Transportation of acoustic information is vital for humans since the very beginning of the human evolution. Hence, reproduction of acoustics has a long tradition in engineering ... Read More
A shift-and-weight method for fast interpolation of probe charge electrostatic potentials
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 ... Read More
Calibration of thermal model to simulate laser assisted bonding process
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 ... Read More
Concept Level Automotive Structural Analysis in COMSOL Multiphysics®
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 ... Read More
THERMO-ELASTIC STUDY OF A SPACE ACTUATOR BALL BEARING SET
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 ... Read More
Numerical Modelling and Validation of Induction Melting of IN713C for Investment Casting
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 ... Read More
In-Situ Scale Inhibitor Interaction with Surface Area of Porous Sandpack: A Numerical Approach.
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 ... Read More
FE-Simulation of PTCA Balloon Catheters
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 ... Read More
Simulation of Nonlinear Optical Absorption in Silicon Optical Waveguide
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 ... Read More
Acoustic manipulation capabilities of a multifrequency AlN based PMUT
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 ... Read More
