    Abstract : The ability to generate accurate approximations of derivatives holds significant importance in numerous scientific fields, including chemistry, economics and fluid mechanics. This thesis is centred around extracting hidden information in data using Smoothness-Increasing Accuracy-Conserving (SIAC) filters. READ MORE

  3. 2. Analysis of High and Low Rossby Wave Phase Speed Events Over Northern Mid-Latitudes

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Emma Rosengren; [2022]
    Keywords : Rossby waves; phase speed; atmospheric blocking; storm track; windstorms; Rossbyvågor; fashastighet; atmosfärisk blockering; lågtrycksbana; vindstormar;

    Abstract : The large-scale, mid-latitude circulation in the upper troposphere is dominated by Rossby waves. The jet stream flows along the wave structure and surface cyclones can be found ahead of the troughs of the waves, propagating eastward. READ MORE

  4. 3. Parametric Study of a Mitral Valve Model for Blood Flow Simulation in the Left Ventricle of the Human Heart

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Adam Skärbo Jonsson; Hanna Kylhammar; [2020]
    Keywords : ;

    Abstract : Tekniska lösningar för diagnostisering och behandling av hjärtsjukdomar är av stort intresse för samhället med anledning att det är en av de främsta dödsorsakerna världen över. Denna avhandling fokuserar på klaffen i hjärtat mellan vänstra förmaken och kammaren, mitralisklaffen, och blodflödet i vänstra kammaren. READ MORE

  5. 4. Steady ideal flows with vorticity in toroidal domains and periodic cylinders

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Gustav Jillbratt; [2020]
    Keywords : Partial differential equations; Euler equation; Vorticity; Fluid dynamics; Mathematics and Statistics;

    Abstract : In a paper from 1970, Lortz constructs rotational solutions to the steady Euler equation in toroidal domains using a fixed point method. We shall review this method and rewrite it using Banach's fixed point theorem. READ MORE

  6. 5. Turbulent Duct Flow with Polymers

    University essay from KTH/Mekanik

    Author : Armin Shahmardi; [2018]
    Keywords : ;

    Abstract : Direct numerical simulation of the turbulent flow in a square duct with polymers has been performed and the results have been compared with the laboratory experiments done at KTH Mechanical engineering department. The polymer suspension is simulated with the FENE-P model, and the numerical results are used to elucidate the mechanism that provides drag reduction and the effect of polymers on the secondary motion which is typical of the turbulent flow in ducts.
