  1. 1. Do viscous flows slip?

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Björn Sjösvärd; [2023-12-21]
    Nyckelord :Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Sammanfattning : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. LÄS MER

  3. 2. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  4. 3. Acoustic Characterization of Catalyst

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Surachit Dokson; [2023]
    Nyckelord :;

    Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER

  5. 4. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Giacomo Semprini Cesari; [2023]
    Nyckelord :Active flow control; drag reduction; numerical simulations; turbulent boundary layer; wings;

    Sammanfattning : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. LÄS MER

  7. 5. Storage period optimization of a viscous nasal spray suspension

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Lili Zsófia Domián; [2023]
    Nyckelord :Rhinocort; viscosity; rheology; thixotropy; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : The number of people suffering from the unpleasant symptoms of allergic rhinitis is increasing due to environmental and other factors. This not only makes life difficult for the individual but also places a heavy burden on society, which is why treatment is needed. LÄS MER
