The Simulation of Motion of a Slider upon a Stator Due to Frictional Force Using COMSOL Multiphysics® Software new

H. B. Nemade[1]
[1]Indian Institute of Technology Guwahati, Guwahati, Assam, India

The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction ... Read More

The Analysis of the Conditions of Flow in the Tundish Performed by a Numerical and Physical Method

T. Merder [1], J. Jowsa [2], A. M. Hutny [2], J. Pieprzyca [1], M. Warzecha [2],
[1] Silesian University of Technology, Katowice, Poland
[2] Czestochowa University of Technology, Czestochowa, Poland

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented ... Read More

Optimization of Drying Step to Obtain Large, Transparent Magnesium-Aluminate Spinel Ceramics

J. Petit [1], L. Lallemant [1],
[1] ONERA, Chatillon, France

To obtain large transparent ceramic samples, we optimized the drying step process using COMSOL Multiphysics®. Indeed, green body's drying in a climate chamber is the critical step when large size and complex shape samples are needed. Then we obtained 75 mm diameter and 10 mm thickness ... Read More

Transient CFD Investigation of a Photocatalytic Multi-tube Reactor

S. Denys [1], J. van Walsem [1], J. Roegiers [1], S. Lenaerts [1],
[1] University of Antwerp, Antwerp, Belgium

As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a ... Read More

The Design of a Novel Roof Tile Shape Using CFD Analysis

M. Bottarelli [1], M. Bortoloni [1], G. Dino [1],
[1] University of Ferrara, Ferrara, Italy

In climates with high temperature and solar radiation, reducing the cooling consumption and increasing the standards of indoor comfort are topics of great importance. The roof plays a key role in controlling the indoor thermal comfort. In ventilated roofs, air flow within the ASV (Above ... Read More

Structural Design of a NFC-Reader-Antenna for Automotive Electronics with FEM Simulation

A. K. Palit [1],
[1] ZF-Lemförder Electronic GmbH, ZF-Friedrichshafen AG. Group, Friedrichshafen, Germany

The design of a right contour/structure of the NFC-antenna is presented. The NFC-reader-antenna is applied later to communicate with the NFC-tag (transponder) of a smart phone placed in the phone box of the car. The NFC-reader-antenna with selected contour is printed directly on the PCB ... Read More

Tunnels, a New Potential Source of Energy: 3D Modeling of a Heat Exchanger within Tunnel Lining
