  1. 1. Prototyping and manufacturing of air-controlled damper unit to improve cooling system operating efficiency for data centers

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Peter Nilsson; [2023]
    Keywords : data center; cooling; server; design; efficiency; model; design; holistic cooling; cooling system; air cooling; differential pressure; wind tunnel; CRAH; datacenter; luftkylning; modell; design; CRAH; kylning; tryck; vindtunnel; server;

    Abstract : More and more people are using the internet for data processing, transfer, and storage. With it comes a higher demand for computational power from data servers. Unsurprisingly, the data center industry is becoming an increasingly large industry that is important for people’s daily lives. READ MORE

  3. 2. Sensor system for pressure measuring over a sail : Construction and implementation of a sail pressure measuring system

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Filip Palm; [2022]
    Keywords : Oceanbird; Sail pressure; KTH; pressure sensor system; Environment; Oceanbird; tryckmätningssystem; miljö; KTH; tryckmätning segel;

    Abstract : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. READ MORE

  4. 3. A Numerical Approach for Wind Tunnel Noise Control

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Hampus Dall; Robert Palm; [2021]
    Keywords : Technical Acoustics; ANC; Active Noise Control; Superposition; Wind Tunnel; Wingsuit; Indoor Wingsuit; Higher Order Modal Acoustic Field Beyond Plane Wave Region; Numerical Acoustic Simulations; Teknisk Akustik; Aktiv Brusreducering; Superposition; Vindtunnel; Flygning med ekorrdräkt inomhus; Högre ordningens akustisk modanalys bortom planvågsteori; Numeriska akustiska simuleringar;

    Abstract : A wind tunnel from the 1950s located in Bromma, Stockholm, once used for military research is today used for commercial activities. Today the tunnel is used for indoor wingsuit flight and the facility has an interest in reducing the overall noise generated by the tunnel. Acoustic measurements indicate noise problems in the 50 Hz range. READ MORE

    Abstract : This study was performed to investigate aerodynamic characteristics of the 37.5% scaled­ down Green Raven MK18 airframe, to evaluate boundary corrections method, and to investigate on support interference. READ MORE

  6. 5. Numerical study of the effects of wind-tunnel conditions on a passenger vehicle in crosswinds

    University essay from KTH/Teknisk mekanik

    Author : Sahil Gupta; Vivek J Shah; [2020]
    Keywords : ;

    Abstract : Wind tunnel tests is a necessity when it comes to study of aerodynamic flow field around vehicle in its development process. However, there are certain limitations on physical wind tunnel tests during vehicle development process. This includes high running costs and interference effects due to blockage and boundary conditions. READ MORE
