Modal Analysis of Rotating Machines

C. Frankrone [1], L. Fromme [1],
[1] Department of Engineering Sciences and Mathematics, Bielefeld University of Applied Sciences, Bielefeld, Germany

Machines with rotating components are prone to vibrations because an imbalance of the rotor would always act as a harmonic excitation force to the machine. Thus oscillations close to the natural frequencies are tried to pass through fast in the run-up and cast-down or even completely ... En savoir plus

COMSOL Multiphysics® Simulation of Functionalized 3D Biocompatible Porous Graphene Composites

E. Lacatus [1],
[1] Polytechnic University of Bucharest (UPB), Bucharest, Romania

Graphene is an allotrope of carbon having the structure of a plane sp2-hybridized atom with a band length of 1.42Å, and representing the basis of any carbonaceous material. This 2D material consisting on pure forms of carbon exhibits high crystalline and electronic quality. Thus, despite ... En savoir plus

Comparison Between COMSOL Multiphysics® and Star-CCM+® Simulation Results and Experimentally Determined Measured Data for a Venturi Tube

E. Weizel [1], A. Diring [1], L. Fromme [1], M. Petry [1]
[1] University of Applied Sciences, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

Numerical simulation tools offer the opportunity to ascertain characteristic values, which are difficult to measure. A possible approach for validating simulation models by easy measurable data and gaining the needed values is described in this study of a Venturi tube. The examination of ... En savoir plus

Uncertainty Assessment and Sensitivity Analysis of Heat Generation within a Lithium-Ion Battery

G. Liebig [1], G. Gupta [1], K. Derendorf [1], C. Agert [1],
[1] DLR Institute of Networked Energy Systems, Oldenburg, Germany

Dedicated work in modeling, simulation and design optimization of Lithium-ion Battery (LIBs) was done in the past decades, and still, the most widely used one for electrochemical processes is the Newman model. [1] The underlying parameters are treated deterministically, but the impact of ... En savoir plus

CFD Analysis of a Stirred Vessel Bioreactor with Double Pitch Blade and Rushton Type Impellers

A. Buss [1,2], A. Suleiko [2,3], K. Rugele [2], J. Vanags [3],
[1] Riga Biomaterials Innovation and Development Centre, Riga Technical University, Riga, Latvia
[2] Institute of General Chemical Engineering, Riga Technical University, Riga, Latvia
[3] Latvian State Institute of Wood Chemistry, Laboratory of Bioprocess Engineering, Riga, Latvia

Stirred tank bioreactors are used to simulate a natural biochemical environment for the optimum growth of cells (i.e. algae, microorganisms or tissues) in microbial and cell culture. Bioreactor types range from small (5 L and less) up to 15000 L systems for large-scale industrial ... En savoir plus

Designing and Implementation of a 4000/5A Current Transformer

O. Ozgonenel [1], S. Eyup [2], U. Kurt [3],
[1] Electrical and Electronic Engineering, Ondokuz Mayis University, Samsun, Turkey
[2] Unitrans Co., Istanbul, Turkey
[3] Electrical and Electronic Engineering, Amasya University, Amasya, Turkey

This paper presents a measurement type 4000/5A current transformer which has 4 primary bars. The magnetic circuit of the prototype can be separable presenting easy installation inside the distribution panel. Time domain and frequency based simulations are obtained and the electric ...
