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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE

  3. 2. First principles investigation of the thermal conductivity of Zr, ZrC, and ZrN

    University essay from KTH/Fysik

    Author : Daniel Karlsson; [2023]
    Keywords : Electron-phonon interaction; Density functional theory; Boltzmann transport equation; first-principles; thermal conductivity; electrical resistivity; Abinit; Phono3py; Elektron-fononväxelverkan; täthetsfunktionalteori; Boltzmanns transportekvation; värmeledningsförmåga; elektrisk resistivitet; Abinit; Phono3py;

    Abstract : The thermal conductivity and electrical resistivity of Zr, ZrC, and ZrN were calculated using first-principles density functional theory (DFT) and the Boltzmann transport equation. The electron-phonon scattering was modeled via the self-energy relaxation time approximation (SERTA), and the phonon-phonon scattering via the analogous single-mode relaxation time approximation (SMRTA).

  4. 3. Numerical simulations using Lattice Boltzmann Method

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

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

    Abstract : 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. READ MORE

  5. 4. Modeling Radiation Induced Degradation of Lattice Thermal Conductivity

    University essay from KTH/Materialvetenskap

    Author : Robin Andersson; [2020]
    Keywords : ;

    Abstract : Nuclear power technology is currently experiencing a revolutionary development process and its utilization is researched and debated throughout the world whereas sustainability is one of the most important topics in the material science arena. Some components in a nuclear power plant are subject to an irradiating environment which will cause significant damage to the material over time. READ MORE

  6. 5. 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
