   Sammanfattning : This dissertation investigates whether northern Sweden's forest-based staple production and maritime activities were increased and altered in any significant ways prior to the expansion which began just before the middle of the nineteenth century. Furthermore, it studies whether certain changes contributed to thecreation of preconditions for the named expansion. LÄS MER

3. 2. Methods and techniques for precise and accurate in-duct aero-acoustic measurements : Application to the area expansion

   Författare :Luck Peerlings; Susann Boij; Hans Bodén; Yves Aurégan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-expansion; Scattering matrix; Multi-microphone method; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : During the design and commissioning of combustion equipment, combustion associated instabilities are commonly encountered. These thermo-acoustic instabilities can cause undesirable noise, vibrations, local thermal and mechanical stresses in the combustor and are prominent in lean combustion. LÄS MER
