  1. 1. Signatures of Dark Matter at the LHC : A phenomenological study combining collider and cosmological bounds to constrain a vector dark matter particle model

    University essay from Uppsala universitet/Högenergifysik

    Author : Anton Olsson; [2022]
    Keywords : Dark matter; particle phenomenology; LHC; MadGraph; standard model; beyond standard model;

    Abstract : Everything that humans have ever touched, created or built something from consists of a type of matter that only makes up 15 percent of the total matter in the universe. The remaining 85 percent is attributed to dark matter, a so far not discovered and non-luminous type of matter. READ MORE

  3. 2. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Josep Plana Riu; [2022]
    Keywords : ;

    Abstract : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. READ MORE

  4. 3. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications

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

    Author : Andreas Eriksson; [2022]
    Keywords : atmospheric dispersion; particle deposition; k-epsilon; RANS; lagrangian particle model; stochastic particle model; OpenFOAM; SIMPLE algorithm; ABL; atmospheric boundary layer; neutral boundary layer; coherent turbulent structures;

    Abstract : In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications.  The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport.

  5. 4. LES modelling of spray combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Arvid Åkerblom; [2021]
    Keywords : Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Abstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

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

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE
