1. Matematiska modeller och datorberäkningar för ytdiffusion
Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaperSammanfattning : I detta arbete undersöks geometriska flöden och hur dessa kan implementeras numeriskt med fasfältsmodeller. Speciellt ligger fokus på ytdiffusion, som är ett geometriskt flöde där ändliga ytor i andra dimensionen konvergerar mot en cirkel och arean bevaras. LÄS MER
2. Thermal and flow field validation of lattice Boltzmann method solver
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : 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. First principles investigation of the thermal conductivity of Zr, ZrC, and ZrN
Master-uppsats, KTH/FysikSammanfattning : 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. Numerical simulations using Lattice Boltzmann Method
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : 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
5. Modeling Radiation Induced Degradation of Lattice Thermal Conductivity
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : 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. LÄS MER
