1. Simulating flow-noise for after-treatment systems
University essay from KTH/Teknisk mekanikAbstract : Modern silencers for heavy vehicle applications are designed to cancel out the sound generated by the effects of combustion and propagation of exhaust gases through the engine after-treatment system. The complex geometry within the compact silencer give rise to self generated (or flow-) noise that contribute to the total sound power radiated at the exhaust outlet. READ MORE

2. Aero and vibroacoustical prediction of the noise generated by turbulent boundary layers
University essay from KTH/MWL Marcus Wallenberg LaboratorietAbstract : Flow noise is a major noise source in the transportation industry from the automotive up to the aircraft industry. The characterization of the aerodynamic excitations and of the structure transmission is of primary interest in order to improve the passenger and crew comfort. READ MORE

3. Identification and modelling of noise sources on a realisticnose landing gear using phased array methods applied tocomputational data
University essay from KTH/MWL Marcus Wallenberg LaboratorietAbstract : Due to the recent development of quieter turbofan engines, airframe noise has started to emerge asthe most important noise source. This is particularly true during the approach/landing phase, whenthe engines are operated at low-thrust levels. READ MORE

4. Noise Radiation from Automotive Turbochargers
University essay from KTH/Farkost och flygAbstract : Turbochargers are now commonly used in modern automotive engines, which increase the density of air entering the engine to produce more power. This device not only greatly improves the degree of engine efficiency, but also reduces the pollutant emissions. However, one of the important issues which must be considered is the noise from turbochargers. READ MORE
