|151-0215-00L||Fundamentals of Acoustics |
Note: The previous course title until HS21 "Engineering Acoustics I"
|4 KP||3G||N. Noiray, B. Van Damme|
|Kurzbeschreibung||This course provides an introduction to acoustics. It focusses on fundamental phenomena of airborne and structure-borne sound waves. The lecture combines theoretical principles with practical insights and interpretations.|
|Lernziel||This course is proposed for Master and PhD students interested in getting knowledge in acoustics. Students will be able to understand, describe analytically and interpret sound generation, absorption and propagation.|
|Inhalt||First, magnitudes characterizing sound propagation are reviewed and the constitutive equations for acoustics are derived. Then the different types of sources (monopole/dipole/quadrupole, punctual, non-compact) are introduced and linked to the noise generated by turbulent flows, coherent vortical structures or fluctuating heat release. The scattering of sound by rigid bodies is given in basic configurations. Analytical, experimental and numerical methods used to analyze sound in ducts and rooms are presented (Green functions, Galerkin expansions, Helmholtz solvers).|
The second part covers elastic wave phenomena, such as dispersion and vibration modes, in infinite and finite structures.
|Skript||Handouts will be distributed during the class|
|Literatur||Books will be recommended for each chapter|
|151-0293-00L||Combustion and Reactive Processes in Energy and Materials Technology||4 KP||2V + 1U + 2A||N. Noiray, F. Ernst, C. E. Frouzakis|
|Kurzbeschreibung||This course will provide an introduction to the fundamentals and the applications of combustion in energy conversion and nanoparticles synthesis. The content is highly relevant for technologies which cannot be electrified such as long distance aviation and shipping, and which will more and more rely on carbon-neutral synthetic fuels.|
|Lernziel||The main learning objectives of this course are: 1. Understand the thermodynamic, fluid-dynamic and chemical kinetics fundamentals of combustion processes. 2. Predict relevant parameters for combustion systems, such as laminar and turbulent flame speeds, adiabatic flame temperature or quenching distance. 3. Understand the causal relations of relevant combustion parameters such as the pressure influence on the laminar flame speed. 4. Analyze the challenges of developing sustainable combustion technologies based on carbon-neutral synthetic fuels.|
|Inhalt||Reaction kinetics, fuel oxidation mechanisms, premixed and diffusion laminar flames, two-phase-flows, turbulence and turbulent combustion, pollutant formation, development of sustainable combustion technologies for power generation, shipping and aviation. Synthesis of materials in flame processes: particles, pigments and nanoparticles. Fundamentals of design and optimization of flame reactors, effect of reactant mixing on product characteristics.|
|Skript||No script available. Instead, material will be provided in lecture slides and the following text book (which can be downloaded for free) will be followed:|
