[1]Pennsylvania State University, University Park, PA, USA

COMSOL Multiphysics software was used to structurally optimize the Wright brothers’ flyer. The flyer was drawn in SolidWorks, imported and meshed in COMSOL. COMSOL Solid Mechanics module was used to analyze the flyer. Four of the sixteen struts were removed yet the structural ... Mehr lesen

Investigating the Performance of Mechanically Ventilated Double-Skin Facades with Solar Control Devices in the Main Cavity

C. G. Galante[1]
[1]Newtecnic Ltd, London, England, UK

The use of ventilated facades may reduce the cooling and heating energy demands of the building. Double-skin facades (DSFs) belong to the wider group of ventilated facades and currently represent one of the most interesting and studied facade systems. The purpose of this study is to ... Mehr lesen

Numerical Modeling of Powder Flow During Coaxial Laser Direct Metal Deposition: Comparison Between Ti-6Al-4V Alloy and 316L Stainless Steel

This paper presents a 3D numerical model to predict the whole process of coaxial powder flow, including the particle stream flow in and below the nozzle and also the laser-particle interaction process. The Particle Tracing Module of COMSOL Multiphysics is used to solve the coupled ... Mehr lesen

Development and Optimization of a Microfluidic Device for Magnetic Field Induced Cell Separation

L. Helmich[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... Mehr lesen

Computational Modeling of Synthetic Jets

D.C. Durán, and O.D. López
Universidad de los Andes, Bogotá, Colombia

A synthetic Jet actuator is a device which moves a fluid in and outside a cavity, through a small aperture, by the continuous oscillation of a diaphragm. The multiphysics interaction between the piezoelectric disk, which deforms due to the alternating voltage, and the fluid makes COMSOL ... Mehr lesen

Modeling of High-Temperature Ceramic Membranes for Oxygen Separation

[1]Chemical and Nuclear Engineering Depart., Universidad Politécnica de Valencia, Valencia, Spain
[2]Instituto de Tecnología Química, Valencia, Spain

Oxygen transfer through ceramic membranes at high-temperature can substantially reduce costs respect to conventional separation methods. With the aim to improve the determination of the properties of the ceramic materials, a lab-scale permeation set-up was modeled using the Chemical ... Mehr lesen

Prediction of Time of Death Using a Heat Transport Model

J.L. Smart[1], and M. Kaliszan[2]
[1]University of Kentucky, Paducah, KY, USA
[2]Medical University of Gdansk, Gdansk, Poland

COMSOL Multiphysics® 4.0 was used to study conductive and convective heat transfer from the human eyeball to the surrounding air. Postmortem temperature decay curves were collected in eyeballs of numerous human corpses. Of course, these curves represent only a portion of the complete ... Mehr lesen
