T1  - Multi-interface level sensors and new development in monitoring and control of oil separators
N2  - In the oil industry, huge saving may be made if suitable multi-interface level measurement systems are employed for effectively monitoring crude oil separators and efficient control of their operation. A number of techniques, e.g. externally mounted displacers, differential pressure transmitters and capacitance rod devices, have been developed to measure the separation process with gas, oil, water and other components. Because of the unavailability of suitable multi-interface level measurement systems, oil separators are currently operated by the trial-and-error approach. In this paper some conventional techniques, which have been used for level measurement in industry, and new development are discussed.

T1  - Temperature measurement to optimise the burning process
N2  - One of the most important parameters in a burning chamber - in power stations, in waste to energy plants - is the temperature. This temperature is in the range of 700-1500 °C - one of the most advanced measuring methods being the acoustic pyrometry with the possibility of producing temperature mapping in one level of the burning chamber - comparable to computer tomography. The results of these measurements discussed in the presentation can be used - to fulfil the legal requirements in the FRG or in the EU - to equalise the temperature in one level of the burning chamber to optimise the steam production (better efficiency of the plant) and to minimise the production of temperature controlled flue gas components (NO, CO a. o.) - to control the SNCR-process if used.

T1  - Platform of Excellence in "Energy and Environment"
N2  - The Ministry of Science and Research in North Rhine-Westphalia created eight platforms of excellence, one in the research area „Energy and Environment“ in 2002 at ACUAS. This platform concentrates the research and development of 13 professors in Jülich and Aachen and of two scientific institutes with different topics: – NOWUM-Energy with emphasis on efficient and economic energy conversion – The Solar Institute Jülich – SIJ – being the largest research institute in the field of renewables at a University of Applied Sciences in Germany With this platform each possible energy conversion – nuclear, fossil, renewable- can be dealt with to help solving the two most important problems of mankind, energy and potable water. At the CSE are presented the historical development, some research results and the combined master studies in „Energy Systems“ and „Nuclear Applications“

N2  - Urban Search and Rescue (USAR) is an active research
field in the robotics community. Despite recent advances
for many open research questions, these kind of systems are
not widely used in real rescue missions. One reason is that such
systems are complex and not (yet) very reliable; another is that
one has to be an robotic expert to run such a system. Moreover,
available rescue robots are very expensive and the benefits of
using them are still limited.
In this paper, we present the Scarab robot, an alternative
design for a USAR robot. The robot is light weight, humanpackable
and its primary purpose is that of extending the
rescuer’s capability to sense the disaster site. The idea is that a
responder throws the robot to a certain spot. The robot survives
the impact with the ground and relays sensor data such as
camera images or thermal images to the responder’s hand-held
control unit from which the robot can be remotely controlled.

T1  - Risiko Smart Home – Angriff auf ein Babymonitorsystem
T2  - Proceedings of DACH Security 2016, Klagenfurt, Austria, September 2016
N2  - Unser Zuhause wird zunehmend intelligenter. Smart Homes bieten uns die Steuerung von Haus- oder Unterhaltungstechnik bequem vom Smartphone aus. Junge Familien nutzen die Technologie, um mittels vernetzten Babymonitorsystemen ihren Nachwuchs von überall aus im Blick zu haben. Davon auszugehen, dass solche Systeme mit einem Fokus auf Sicherheit entwickelt wurden, um die sehr persönlichen Daten zu schützen, ist jedoch ein Trugschluss. Die Untersuchung eines handelsüblichen und keineswegs billigen Systems zeigt, dass die Geräte sehr einfach kompromittiert und missbraucht werden können.

T1  - Comparison and evaluation of blade element methods against RANS simulations and test data
T2  - CEAS Aeronautical Journal
N2  - This paper compares several blade element theory (BET) method-based propeller simulation tools, including an evaluation against static propeller ground tests and high-fidelity Reynolds-Average Navier Stokes (RANS) simulations. Two proprietary propeller geometries for paraglider applications are analysed in static and flight conditions. The RANS simulations are validated with the static test data and used as a reference for comparing the BET in flight conditions. The comparison includes the analysis of varying 2D aerodynamic airfoil parameters and different induced velocity calculation methods. The evaluation of the BET propeller simulation tools shows the strength of the BET tools compared to RANS simulations. The RANS simulations underpredict static experimental data within 10% relative error, while appropriate BET tools overpredict the RANS results by 15–20% relative error. A variation in 2D aerodynamic data depicts the need for highly accurate 2D data for accurate BET results. The nonlinear BET coupled with XFOIL for the 2D aerodynamic data matches best with RANS in static operation and flight conditions. The novel BET tool PropCODE combines both approaches and offers further correction models for highly accurate static and flight condition results.

T1  - Simulation of transient voltage curve of a house-load operation net-work of large power plant by a lightning strike in a high-voltage over-head line closed to the power plant
N2  - 8. VDE/ABB-Blitzschutztagung, 29. - 30. Oktober 2009 in Neu-Ulm. Blitzschutztagung <8, 2009, Neu-Ulm> Berlin : VDE Verl. 2009 Großkraftwerke können durch Blitzentladungen mit potentiellen Auswirkungen auf deren Verfügbarkeit und Sicherheit gefährdet werden. Ein sehr spezielles Szenario, welches aus aktuellem Anlass zu untersuchen war, betrifft den kraftwerksnahen Blitzeinschlag in die Hochspannungs-Freileitung am Netzanschluss der Anlage. Wird nun noch ein sogenannter Schirmfehler unterstellt, d.h. der direkte Blitzeinschlag erfolgt in ein Leiterseil des Hoch- bzw. Höchstspannungsnetzes und nicht in das darüber gespannte Erdseil, so bedeutet dies eine extreme elektromagnetische Einwirkung. Der vorliegende Beitrag befasst sich mit der Simulation eines solchen Blitzeinschlages und dessen Auswirkungen auf den Netzanschluss und die Komponenten der elektrischen Eigenbedarfsanlagen eines Kraftwerks auf den unterlagerten Spannungsebenen. Die dabei gewonnenen Erkenntnisse lassen sich ohne Einschränkungen auf Industrieanlagen mit Mittelspannungs-Netzanschluss und ohne eigener Stromversorgung übertragen.
N2  - Lightning discharge can endanger large power plants with potential influence on their availability and reliability. A very special scenario, which was currently to analyse, is the lightning strike close to the high-voltage overhead line at the grid of the power plant. Supposing a failure of shielding and that the lightning strike goes directly into the line then the elec-tromagnetic effect is extremely high. The following article gives attention to the simulation of lightning strike and their effects to the connection with the grid and the components of the house-load operation of a large power plant especially to the lower voltage level sections. These results are transferable to industrial plants which have no own power supply.
