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. 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
4. Particle-Size Effects on the Enhanced Diffusion of Tracer Particles in Microswimmer Suspensions
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fysikalisk kemiSammanfattning : 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. LÄS MER
5. Collective behaviour in suspensions of pushers and pullers
Master-uppsats, Lunds universitet/Biofysikalisk kemiSammanfattning : Microswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. LÄS MER
