CFD Based Optimisation of a Laboratory Scale Silo

A. Egedy [1], A. Rado [1],
[1] University of Pannonia, Faculty of Engineering, Veszprém, Hungary

The flow simulation of solid, particulate materials is still challenging, even though estimations show that three-quarters of products and raw materials are present as granules form in the industry. We can think of grain in the agriculture, raw materials of the glass industry, granulated ... Mehr lesen

3D Modeling of Urban Areas for Built Environment Applications Using COMSOL

J. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

This paper presents the modeling and simulation results of wind velocities in urban areas. The main idea was to build random generated urban areas for studying the influence of different urban geometries, from relative open to more dense, on wind profiles. The Spalert-Allmaras turbulent ... Mehr lesen

Implementation of a Modified Anisotropic Creep Model for Clays with Use of the Physics Builder

M. Karlsson [1], J. Yannie [1],
[1] Chalmers University of Technology, Gothenburg, Sweden

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user ... Mehr lesen

Simplified CFD Modeling of Air Pollution Reduction by Means of Greenery in Urban Canyons

[1] University of Genova, Dept. of Sciences for Architecture, Genova, Italy
[2] University of Bologna, Dept. of Industrial Engineering, Bologna, Italy
[3] University of Genova, Dept. of Sciences of Earth, Environment and Life, Genova, Italy

As known, air quality in urban areas is dramatically affected in particular by the noteworthy presence of respirable suspended particulate matter (such as PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC), which are mainly due to traffic-induced emissions. On the ... Mehr lesen

3D-Printed Microfluidic Chip System for Dielectrophoretic Manipulation of Colloids

[1] Heilbronn University of Applied Science, Kuenzelsau, Germany
[2] University of Applied Science, Augsburg, Germany

INTRODUCTION: Microfluidics, as a crucial technology of recent years, enables numerous applications for Point-of-Care-Testing such as Lab-on-Chip-Systems (LOC) or Micro-Total-Analysis-Systems (µTAS) and is exceptionally well-suited for cell sorting or DNA trapping. Especially the ... Mehr lesen

Simulation of the Electrical Properties of Conductive ITO Thin Films by Finite Element Analysis

R. A. Gerhardt [1], N. Xia [1], Y. Jin [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

Finite element analysis (FEA) can be used to study the electrical properties of conductive ITO thin films. Previous studies have been done on insulating thin films deposited on conductive substrates [1,2]. It was found that changes of electrode size and film thicknesses can cause huge ... Mehr lesen

Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corp., Hauppauge, NY, USA

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... Mehr lesen

Foundational Undergraduate Teaching and Research Tools In Thermoelectrics Using COMSOL Multiphysics®

D. Buna [1], L. Hoxha [1], D. Tafone [1]
[1] School of Theoretical and Applied Science, Engineering Physics, Ramapo College of New Jersey, Mahwah, NJ, USA

COMSOL Multiphysics® can play a crucial role in jumpstarting undergraduate research programs in physics and engineering at colleges with limited financial support and small faculty size. The engineering physics program at Ramapo College of NJ has 48 majors and 4 full time faculty with ... Mehr lesen

Implementation of COMSOL Multiphysics® in Simulink® S-Functions, Revisited

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

COMSOL Multiphysics® has standard facilities to export models to SimuLink®. Normally, the standard export works well if the solvers, available in SimuLink, can handle the problem. However, if a model in COMSOL Multiphysics® needs special solvers, for example airflow or other non-linear ... Mehr lesen

Analyzing Fluid Shear Stress in the RCCS: Applications for 3D Cell Culture in Simulated Microgravity
