  1. 1. Thermal and flow field validation of lattice Boltzmann method solver

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :André Skagius-Kallin; [2023]
    Nyckelord :Lattice Boltzmann method; heat transfer; flow field;

    Sammanfattning : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. LÄS MER

  3. 2. Numerical simulations using Lattice Boltzmann Method

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Mouadh Boubaker; [2021]
    Nyckelord :Computational fluid mechanics; lattice Boltzmann method; numerical simulations; Beräkningsvätskemekanik; galler Boltzmann -metoden; numeriska simuleringar;

    Sammanfattning : The lattice Boltzmann method (LBM) is widely studied andused in the last years to replace the conventional numerical solvers forthe Navier-Stokes equations. In this work, a general introduction tofluid dynamics equations and the changes when the flow is a reactivemulti-species one will be given first. LÄS MER

  4. 3. Gone With the Headwind. Characterizing Erosion Using Lattice-Boltzmann Method : and its Implication in Planet Formation

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Lukas Cedenblad; [2019]
    Nyckelord :Erosion; Planet formation; Lattice-Boltzmann;

    Sammanfattning : Erosion has a long history in science and is used in many different fields today, for example in geology for coastal erosion and in the oil industry for pipe erosion. It is very difficult to study erosion both analytically. Numerically it is difficult due to moving and shape-changing boundaries. LÄS MER

  5. 4. Real-time Thermal Flow Predictions for Data Centers : Using the Lattice Boltzmann Method on Graphics Processing Units for Predicting Thermal Flow in Data Centers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Johannes Sjölund; [2018]
    Nyckelord :data center; airflow; computational fluid dynamics CFD ; lattice boltzmann method LBM ;

    Sammanfattning : The purpose of this master thesis is to investigate the usage of the Lattice Boltzmann Method (LBM) of Computational Fluid Dynamics (CFD) for real-time prediction of indoor air flows inside a data center module. Thermal prediction is useful in data centers for evaluating the placement of heat-generating equipment and air conditioning. LÄS MER

  7. 5. Turbulent flow control via nature inspired surface modifications

    Master-uppsats, KTH/Mekanik

    Författare :Miguel Beneitez; Johan Sundin; [2017]
    Nyckelord :flow control; DNS; lattice-Boltzmann; surface coating; friction drag; surface structures; superhydrophobic; porous; fibers; micropillars;

    Sammanfattning : Many of the flows in nature are turbulent. To modify turbulent flows, nature serves itself with different types of coatings. Sharks have riblets-like structures on their skin, fishes have slime with polymers and the surface of the lotus flower has superhydrophobic properties. LÄS MER
