  1. 1. Demonstration station for open water channel flow

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : David Bayat; Fabian Grönvik; [2020]
    Keywords : ;

    Abstract : Once a year an event is being held at the fluid physics lab at KTH. One of the main purposes of this event is to awaken an interest in the visiting students from other universities, by demonstrating fluid physics phenomena. Showing the transition from laminar to turbulent flow in an open water channel is one of the demonstrations. READ MORE

  3. 2. Particle-Size Effects on the Enhanced Diffusion of Tracer Particles in Microswimmer Suspensions

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fysikalisk kemi

    Author : Andre Nüsslein; [2020]
    Keywords : Microswimmers; Soft Matter; Tracer Particles; Lattice-Boltzmann; Simulation; Physics and Astronomy;

    Abstract : Active suspensions of microswimmers such as bacteria or microalgae are found in oceans or lakes, and within living organisms, such as the human body. These suspensions can exhibit complex flow patterns and enhanced diffusion of passive tracer particles due to the advection from the long-ranged dipolar flow fields of the swimmers. READ MORE

  4. 3. Fast Simulations of Star Cluster Evolution

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Lina Warntoft; [2019]
    Keywords : star cluster simulation numerical method; Physics and Astronomy;

    Abstract : The evolution of globular star clusters tells the history of the formation of galaxies, how stellar streams might have formed and how the future of the Universe might look like. Although the general theoretical background of the evolution is well understood, it is difficult to conduct accurate and realistic computer simulations of objects containing thousands of interacting bodies.

  5. 4. Influence of Sample Preparation on Portable XRF-analyses of Aeolian Sediments: a Case Study

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Markus L. Fiola; [2017]
    Keywords : portable XRF; loess; sediment; bärbar XRF; lössjord; sediment;

    Abstract : The geochemical composition of aeolian sediments like windblown dust particles is of major importance for the exploration of dust origin and weathering conditions. This allows for the reconstruction of dust transport pathways and thus wind directions and palaeoclimate conditions. READ MORE

  6. 5. A Monte Carlo study of the particle mobility in crowded nearly one-dimensional systems.

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ahlberg Sebastian; [2014]
    Keywords : Molecular crowding; Gillespie s algorithm; Random walk; Nearly 1D-model; Particle diffusion;

    Abstract : The study of crowding effects on particle diffusion is a large subject with implications in many scientific areas. The studies span from pure theoretical calculations to experiments actually measuring the movement of proteins diffusing in a cell. READ MORE
