Numerical Study of Thermal Evaporation Unit for Phase Change of Liquid Hydrogen Peroxide to Vapor

Z. Jildeh [1], [2], [3], C. Hollenbeck [1], P. Kirchner [1], T. Wagner [2], P.H. Wagner [3], M.J. Schöning [2]
[1] Imagine Engineering GmbH, 50126 Bergheim, Germany
[2] Institute of Nano- and Biotechnologies (INB), FH Aachen, Campus Jülich, 52428 Jülich, Germany
[3] Soft Matter and Biophysics, Catholic University Leuven, 3001 Leuven, Belgium

Hydrogen peroxide (H2O2) vapor is a preferred medium of sterilization in different fields of industry. Among the fact that it dissociates to oxygen and water (environmentally-friendly), H2O2 vapor possesses strong mircobicidal and sporicidal characteristics. As such, the use of H2O2 ... Read More

A Simulation App for Determining How Best to Cool a Beer Bottle

J. Richter[1], T. Hilbig[1], C. Schröder[1]
[1]University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

The scope of this project was the creation of a short and comprehensive tutorial for the use of COMSOL® Application Builder for students at the University of Applied Sciences Bielefeld. The tutorial is based on the everyday life “problem” how to cool a beer bottle most efficiently. It ... Read More

Simulation of Beverage Refrigeration with Dependence on Container Shape, Material and Orientation

S. Bekemeier[1], L. Fromme[1], A. Genschel[1], K. Kröger[1]
[1]University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

Adequate cooling of beverages is a major issue in planning of several types of events, e.g. poster sessions at conferences. One crucial factor is the time needed to cool beverages from its initial temperature to the desired drinking temperature. We present a way to determine a close ... Read More

Finite Element Modeling of Dispersion and Thermal Noise in Whispering-Gallery Mode Cavities

N. M. Kondratiev [1], M. L. Gorodetsky [1]
[1] Russian Quantum Center (RQC), Moscow, Russia

This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence ... Read More

Thermal Clothing Engineering Using a COMSOL® Simulation App

B. Van Der Smissen [1], S. Vasile [2],
[1] University College Ghent, Faculty of Science and Nature, Mechatronics, Ghent, Belgium
[2] University College Ghent, Science and Nature, Fashion, Textile and Wood Technology, Ghent, Belgium

In this paper the development of a COMSOL® app for the engineering design of thermal quality clothing has been started. The software architecture is developed for different design strategies. Specific design requirements lead to different simulation models for the clothing wearing system ... Read More

Design of a Heat Trap for Optimal Heat and Current Conduction on Soldering Pads

F. Figueroa [1], P. Aguirre [1],
[1] STW, Sensor Technik Wiedemann GmbH, Kaufbeuren, Germany

This poster presents an evaluation study of a couple of heat trap designs, analyzing the generation of Joule heating and heat dissipation characteristics. Through parametric simulations of the heat traps varying geometries, it is possible to see the generated temperature difference at a ... Read More

Model of Sub-Surface Heat Rejection in Alternative Cooling Systems

E. Holzbecher [1], T. Manchester [2],
[1] German University of Technology in Oman (GUtech), Halban, Oman
[2] Univ. Utrecht, Utrecht, Netherlands

A model is presented for heat rejection in the subsurface. Geometries of different dimension are coupled by linear and general extrusions. In that way it is possible to deal with multi-scale physical set-up. An example shows the high influence of groundwater flow. Read More

Finite Element Evaluation of the Strength of Silicide-Based Thermoelectric Modules

A. Miozzo [1], S. Boldrini [1], A. Ferrario [1], M. Fabrizio [1],
[1] Institute of Condensed Matter Chemistry and Techologies for Energy - National Research Council of Italy, Padova, Italy

Silicide-based thermoelectric modules (TEMs) for power generation operate at mid-high temperature range. In the operating conditions, thermal stresses in materials with different coefficient of thermal expansion may reduce the mechanical strength of the modules. In this work, a finite ... Read More

Investigation of Ablation of a Copper Surface Caused by 220 Nanosecond Laser Pulse

M. Dillmann [1], B. Braun [1], M. Kottcke [1],
[1] Technische Hochschule Georg-Simon-Ohm, Nuernberg, Germany

This work investigates the ablation of a copper surface caused by the irradiation of a 220 ns laser pulse. Our focus is on the heat transport within the copper and takes the proceeding vaporization of surface substance into account. Our model ignores plasma dynamics and simulates the ... Read More

Numerical Design of a Test Plant for Dynamic Analysis of High Temperature Thermoelectric Generators

M. Rohne [1], A. Schlott [1], V. Pacheco [1], J. Meinert [1],
[1] Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM, Branch Lab Dresden, Dresden, Germany

Thermoelectric generators (TEG) use Seebeck’s effect to directly convert heat into electricity. TEG represent, therefore, a promising option for energy harvesting of waste heat, for example in car exhaust systems. To investigate the dynamic behavior of high temperature TEG, a test ... Read More
