  1. 1. Experimental Studies on the Aeroacoustics of Low-Speed Axial Fans

    Författare :Michail Vourakis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-speed axial fans; electric fans; experimental; laser Doppler anemometry; low-pressure axial fans; cooling fan; aeroacoustics; rotating ring;

    Sammanfattning : Low-speed axial fans are used in thermal management systems of internal combustion and electric vehicles. These systems are compact, cost-effective, all while addressing safety concerns. On the downside, fan operation leads to flow induced noise. LÄS MER

  3. 2. Aerodynamic Design and Installation Effects of Automotive Electric Cooling Fans

    Författare :Debarshee Ghosh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blade Element Momentum BEM ; low-pressure axial fans; electric cooling fans; automotive thermal management; CFD simulations; upstream blockage; fans in parallel;

    Sammanfattning : Electric cooling fans play a crucial role in automotive thermal management. They generate the airflow required for heat rejection from the expended coolant circulating within the heat exchanger. This thesis focuses on the aerodynamic design and installation effects of electric cooling fans or "E-fans". LÄS MER

  5. 4. Jag och mitt fanskap : vad musik kan göra för människor

    Författare :Eva Kjellander Hellqvist; Sweden Örebro University; []
    Nyckelord :HUMANIORA; HUMANITIES; Fan; Fandom; Identity; Popular music; Grounded theory; Subcultural capital; Experiences; Learning; Meaning; Authenticity.; Fans; Fanskap; Identitet; Socialisering; Musikvetenskap; Musicology;

    Sammanfattning : This dissertation aims to find further understanding of how people with special interest in a certain artist utilise music and the fact that they are fans in their everyday lives. I have opted to study two fans included in each group selected for this study: Kiss, Status Quo and Lasse Stefanz, one male and one female fan belonging to each respective group. LÄS MER

  7. 5. Effektivisering av pump- och fläktdrifter i byggnader. Elanvändning och systemlösningar

    Författare :Caroline S Markusson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; damper; efficiency; electric energy; authority; demand; control; variable speed; valve; heating; cooling; fans; electric motors; ventilation; pumps;

    Sammanfattning : In this licentiate work the energy savings potential by more efficient pump and fan operation in buildings has been examined. The national savings potential in Sweden has been estimated based on available statistics and on information gained in a limited inventory. The estimated energy use for pump operation in residential and commercial (i.e. LÄS MER
