2. 1. Turbomachinery Aeroacoustic Calculations using Nonlinear Methods

   Author : Martin Olausson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear; CFD; Time Spectral; CAA; Ffowcs-Williams Hawkings; Broadband; Time lag; Computational Aeroacoustics; Fan-Noise; Rotor-Stator interaction; Buffer layer; Oscillating sphere; Newton-GMRES; Computational Fluid Dynamics; Acoustic analogies; Sponge; Counter-Rotating Propfan; Harmonic Balance Technique; Tone; FWH; Chorochronic periodicity; Hybrid RANS LES;

   Abstract : Noise regulations for aircraft that fly over populated areas are becoming continuously stricter. This in combination with increasing computational capabilities has boosted interest in aeroacoustic computations in the aerospace industry. READ MORE

4. 2. Towards a Flexible Monte Carlo Calibration of a Whole Body Counter Spectrometer System - Highlighting the Need of Increased Model Complexity for Large Plastic Scintillators

   Author : Jenny Nilsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Whole body counters, WBC, can be used for fast and accurate screening and follow-ups in the case of an emergency situation involving ionizing radiation given that the WBC calibration method is fast and versatile. A Monte Carlo model of a WBC system could meet these requirements under the condition that the model is an accurate description of the WBC system. READ MORE

5. 3. New Cu-I cluster compounds with luminescent properties

   Author : Ehsan Jalilian; Sven Lidin; Torbjörn Gustafsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Copper I iodide; structure determination; luminescence; TDDFT; Materials chemistry; Materialkemi; Materials Chemistry; materialkemi;

   Abstract : The aim of this thesis has been to investigate how the synthesis route, choice of solvent and counter-ions effects the crystallization of Cu(I)I systems, and to investigate the correlation between the structure and luminescence properties of the systems. In order to do so a series of compounds based on an anion containing Cu(I)I, stabilized by organic cations have been produced. READ MORE

7. 5. Black liquor gasification : burner characteristics and syngas cooling

   Author : Mikael Risberg; Mats Lindblom; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : Black liquor gasification at high temperature is a promising alternative to the conventional recovery boiler process used in chemical pulp mills today. Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel.
