  1. 1. Validation of CFD simulation with PIV measurements for Open Rotor Noise Predictions

    M1-uppsats, KTH/Mekanik

    Författare :THOMAS JEAN BERNARD POMMIER; [2015]
    Nyckelord :;

    Sammanfattning : CROR means Contra--‐Rotating Open Rotor. Its efficiency is better than usual in aeronautics thanks to its geometry (open rotor and thus high bypass ratio) but also by adding a second rotor. Indeed it enables to recover the swirl loss of the first rotor. However, this engine is rarely used today in civil aviation for acoustic reasons. LÄS MER

  3. 2. Two Dimensional Design of Axial Compressor - An Enhanced Version of LUAX-C

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Daniele Perrotti; [2013]
    Nyckelord :Axial Compressor LUAX-C; Technology and Engineering;

    Sammanfattning : The main scope of this thesis is to have a strong tool for a preliminar design and sizing of an axial compressor in a bi-dimensional way, this means that all the parameters are referred to the hub, to the midspan and to the tip of the blade. This goal has been reached improving a pre existent MatlabTM code based on a monodimensional design. LÄS MER

  4. 3. Plant Experiment Using a Swirl Blade in the Uphill Teeming Process

    Master-uppsats, KTH/Materialvetenskap

    Författare :Jennie Svensson; [2011]
    Nyckelord :Swirl Blade; Ingot Casting; Uphill Teeming; Plant Trials; Inclusion;

    Sammanfattning : The purpose of this thesis has been to evaluate the use of a swirl blade in the uphill teeming process through plant trials. Two series of trials were carried out at Scana Steel Stavanger AS. In the trials a divergent entrance nozzle with a 62° outlet angle were used when casting duplex stainless steel on a base plate with two 6.2 tons ingots. LÄS MER

  5. 4. Förrotation till omrörare

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Staffan Melin; Johannes Roselius; [2007]
    Nyckelord :;

    Sammanfattning : The primary function of a mixer is to keep a fluid in constant motion. All mixing applications require varying degrees of small-scale turbulence and bulk flow. The performance of a submersible mixer is measured by the thrust that it produces, while the strength of the bulk flow is dependent on the total amount of installed thrust. LÄS MER
