  1. 1. Ram pump hydraulic air test. Pressure conditions and flow measurements: Experimental research and case study

    Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Paula María Arizcun Zúñiga; [2018]
    Nyckelord :Ram pump; water hammer; pressure; efficiency; installation; drive pipe; delivery pipe; impulse valve;

    Sammanfattning : This study consists of the development of a ram pump, which will allow the pumping of water without the need of external energy sources. It is considered an analysis of interest since, once it is finished; it can be applied in reality improving and facilitating different activities related to agriculture and health. LÄS MER

  4. 3. Parametric Ram Air Channel Model for Flow Optimization

    Master-uppsats, Fluida och mekatroniska system; Tekniska högskolan

    Författare :Chetan Kumar Nangunoori; Ravichandra Kumar Kumar Bhaskar; [2012]
    Nyckelord :;

    Sammanfattning : Ram air channel or NACA channel is used to direct the ambient air for various purposes in an aircraft, such as pressurizing the cabin or as a coolant to heat exchangers and even more other applications like a cooling of the coolant. It is designed; such that it supplies the required amount of ambient air for various operations as mentioned, even aero-dynamical features should be taken into consideration while designing. LÄS MER

  5. 4. Skadeanalys och omkonstruktion av HMS Belos A-ram

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Nyckelord :;

    Sammanfattning : In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. LÄS MER

  7. 5. Aerodynamic Investigation of Air Inlets on Aircrafts with Application of Computational Fluid Dynamics

    M1-uppsats, Akademin för innovation, design och teknik

    Författare :Marcus Lejon; [2011]
    Nyckelord :Aerodynamic; Aerodynamics; CFD; Airbus;

    Sammanfattning : Air inlets in some form are used on all commercial airliners today. The type of air inlet investigated in this report is a NACA inlet submerged into a surface. This surface is within this thesis a test section wall of a wind tunnel. The considered wind tunnel is TWG in Göttingen (Germany) that operates in transonic speeds. LÄS MER
