2. 1. Numerical Simulations of Noise Reduction Devices for Aero Engines

   Author : Haukur Hafsteinsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic liner; G3D; CAA; CFD; CD-nozzle; LES;

   Abstract : Increasing air traffic and denser population around airports have led to stricterregulations on aircraft noise. The engine is the main source of noise of jet aircraft.Decreasing jet engine noise can in some cases reduce sonic fatigue andthereby increase the engine lifetime. READ MORE

4. 2. Study of Supersonic Jet Noise Reduction using LES

   Author : Haukur Hafsteinsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; G3D; Supersonic Jet; PIV; CD-nozzle; CFD; Compressible flow; CAA; Noise Reduction; LES; Flow Control;

   Abstract : Increases in air traffic and denser population around airports have led to stricterregulations on aircraft noise. High noise levels from high-speed aircraft can causehearing damage in pilots and the airfield personnel. The engine is the main sourceof noise of all jet aircraft and is therefore a key component for improvement. READ MORE
