2. 1. Experimental and Numerical Multi-port Eduction for Duct Acoustics

   Author : Stefan Sack; Abom Mats; Phillip Joseph; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; aeroacoustics; flowacoustics; multi-ports; orifice; silencer; experiment; numeric; IDDES; LNSE; optimization; test rig; Monte Carlo; Teknisk mekanik; Engineering Mechanics;

   Abstract : Sound generation and propagation in circular ducts for frequencies beyond the cut-on frequencies of several higher order acoustic modes is investigated. To achieve this, experimental and numerical set-ups are designed and used to research aeroacoustic interactions between in-duct components and to conceive noise mitigation strategies. READ MORE

4. 2. Railway tread braking temperatures - Numerical simulation and experimental studies

   Author : Shahab Teimourimanesh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway tread braking; finite element analysis; railway wheels; rail chill; hot spots; frictional heating; heat partitioning; metro; field experiment; rig experiment;

   Abstract : Tread (block) braking is still one of the most common braking systems on railway vehicles. The action is carried out by pressing brake blocks against the tread of a wheel, which is also in rolling contact with the rail. READ MORE

5. 3. Design, Optimization and Evaluation of a Transonic Aeroelastic Rig

   Author : Simeng Tian; Andrew R. Martin; Mauricio Gutierrez Salas; Dieter Peitsch; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transonic compressor; Aeroelastic rig; Design; CFD; Unsteady flow; Energiteknik; Energy Technology;

   Abstract : The compressor is one of the most essential components of a modern turbomachinery engine. This component is exposed to vibrations that without proper design can damage structural integrity and lead to failure. READ MORE
