  1. 1. Efficiency of radial piston hydraulic motors

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jennifer Eriksson; [2023]
    Keywords : Efficiency; Loss mechanics; MATLAB; Simulation model; Radial piston hydraulic motor;

    Abstract : In a world with high energy cost, the efficiency of motors becomes increasingly important. Thereby, the understanding of loss mechanics is of great significance and having accurate simulation models for the efficiency of motors is crucial. READ MORE

  3. 2. Generating Perturbative Solutions for Slowly Rotating Perfect Fluids Using the Hartle Scheme

    University essay from Umeå universitet/Institutionen för fysik

    Author : Elin Johansson; [2023]
    Keywords : ;

    Abstract : In this thesis, we study slowly rotating relativistic stars by modeling them as perfect fluids. The Hartle formalism is used to perturb a spherically symmetric static solution into slow rotation and the corresponding field equations to second order are presented. READ MORE

  4. 3. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Hjalmar Holmström; [2022]
    Keywords : BEC; Bose-Einstein condensate; quantum fluid; Quantum mechanics; LHY; LHY-fluid; Lee-Huang-Yang; Rotating BEC; BEC droplet; Physics and Astronomy;

    Abstract : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

  5. 4. Development of a Flow Dependent Chemical Reaction Model using CFD

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

    Author : Martin Östman; [2022]
    Keywords : CFD; Fluid mechanics; Rotating Bed Reactor; Ansys Fluent; Decolorization; CFD; Strömningsmekanik; Roterande Bäddreaktor; Ansys Fluent; Avfärgningsprocess;

    Abstract : In many technical applications chemical reactions are used. One of these is a so called decolorization, in which an ion exchange resin is used to remove a dye from water. To apply this decolorization technique a Rotating Bed Reactor, or RBR for short, can be used. It is filled with the ion exchange resin and spun inside the water. READ MORE

  6. 5. PIV measurements of rotational flow in a porous medium : A masters thesis in fluid dynamics and experimental mechanics

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

    Author : Björn Skarman; [2022]
    Keywords : PIV; particle image velocimetry; velocimetry; refractive index matching; porous medium; rotational flow;

    Abstract : The purpose of this work is to test the feasibility of using particle image velocimetry(PIV) for measurements of flow through a porous medium, more specifically in this casea rotating bed reactor S3. The results from experiments preformed can then be usedto validate and improve computational fluid dynamics models. READ MORE
