  1. 16. Rheology of dense particle suspensions in linear over-damped flow

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Salar Zamani Salimi; [2021]
    Nyckelord :;

    Sammanfattning : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.

  3. 17. Simultaneous Bayesian parameter estimation and particle-tracking including calculation of mis-linking probabilities

    Magister-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Lennart Golks; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Since 1994 super-resolution microscopes enable us to visualize processes in the nanome- ter regime where bio-molecules work. Consequently, there is a great need for methods analyzing the generated data to transfer the motion of molecules, seen as white dots, into trajectories. LÄS MER

  4. 18. The Ratio of Reality : A study of the gyromagnetic ratio in theories ranging from classical mechanics to string theory

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Daniel Nilsson; [2021]
    Nyckelord : Quantum field theory ; String theory ; Dirac equation ; Dirac theory ; Dirac; gyromagnetic; ratio; g-factor; Kvantfältsteori; strängteori; Dirac; g-factor; gyrmagnetisk kvot ;

    Sammanfattning : In this project a theoretical study of the so called gyromagnetic ratio was done by investigating classical mechanics, Dirac theory and string theory. The gyromagnetic ratio is a constant term appearing in the coupling between angular momentum and magnetic moment for a particle. LÄS MER

  5. 19. Study of flow fields in mixing tanks with particles using CFD

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sergio Poveda Ruiz; [2021]
    Nyckelord :Keywords: Solid-liquid mixing; particle suspension; aseptic tanks; stirrer geometries; flow fields; URANS; particle modeling; LPT; DEM.; Technology and Engineering;

    Sammanfattning : The demand for food products with particles has increased in the last decades. Among them, yoghurt with fruit pieces or cereals can be found. Thus, the food processing industry is facing important challenges to offer these products to meet the quality requirements. LÄS MER

  7. 20. Brownian Motion and the Dirichlet Problem

    Kandidat-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Anton Palets; [2021]
    Nyckelord :Brownian motion; Dirichlet; Dirichlet problem; Harmonic function; Strong Markov property; Stopping time; Cone condition; Brownian motion construction; Blumenthal; Mathematics and Statistics;

    Sammanfattning : In this Bachelor's thesis, a solution to the Dirichlet problem using Brownian motion is given. Brownian motion is constructed using Kolmogorov's existence and continuity theorems. Blumenthal's zero-one law and the strong Markov property in various formulations are proven. LÄS MER
