    Sammanfattning : The first part of the investigation is related to the heat transfer and fluid flow problem inside ribbed ducts with a square cross section. The typical applications of this problem are in the cooling of gas turbine blades and guiding vanes. The second part is related to application of intercoolers in gas turbine systems. LÄS MER

  5. 4. Noise from Train Cooling Fans

    Författare :Yan Jiang; Mats Åbom; Thomas Carolus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Sammanfattning : This thesis concerns a study undertaken on a railway vehicle cooling fan system. Several design modifications were proposed and tested in the laboratory in order to evaluate different noise control measures. The most effective noise control measure involving combining lots of different measures gave 7 dB(A) noise reduction. LÄS MER
