|Mechanical and Process Engineering
|Engineering Acoustics I
|N. Noiray, B. Van Damme
|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.
|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.
|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.
|Handouts will be distributed during the class
|Books will be recommended for each chapter
|Combustion and Reactive Processes in Energy and Materials Technology
|2V + 1U + 2A
|N. Noiray, F. Ernst, C. E. Frouzakis
|The students should become familiar with the fundamentals and with application examples of chemically reactive processes in energy conversion (combustion engines in particular) as well as the synthesis of new materials.
|The students should become familiar with the fundamentals and with application examples of chemically reactive processes in energy conversion (combustion engines in particular) as well as the synthesis of new materials. The lecture is part of the focus "Energy, Flows & Processes" on the Bachelor level and is recommended as a basis for a future Master in the area of energy. It is also a facultative lecture on Master level in Energy Science and Technology and Process Engineering.
|Reaction kinetics, fuel oxidation mechanisms, premixed and diffusion laminar flames, two-phase-flows, turbulence and turbulent combustion, pollutant formation, applications in combustion engines. 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. Tailoring of products made in flame spray pyrolysis.
