6. Lid driven cavity flow using stencil-based numerical methods
Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : In this report the regular finite differences method (FDM) and a least-squares radial basis function-generated finite differences method (RBF-FD-LS) is used to solve the two-dimensional incompressible Navier-Stokes equations for the lid driven cavity problem. The Navier-Stokes equations is solved using stream function-vorticity formulation. LÄS MER
7. Deep learning for non-intrusive sensing in turbulence with passive scalars
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. LÄS MER
8. An overlapping mesh based splitting method for the incompressible Navier-Stokes equations
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : We present an overlapping mesh based splitting method for solving the incompressible Navier-Stokes equations on unfitted mesh settings. The developed method is based on Nitsche’s method for weakly imposing the interface condition between the overlapping meshes, and it uses a ghost penalty approach for stabilizing the cut elements produced by the mesh intersection.

9. A Simulation of Landslide-Generated Waves Using a Fully Implicit ISPH
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Smoothed Particle Hydrodynamics (SPH) is used to study the mechanisms of landslide-generated waves. As the landslide dynamics and the evaluation of impact forces acting on water are most important, landslide is modelled as a highly viscous fluid. Incompressible SPH (ISPH) is used for fluid simulation. LÄS MER
10. Analyzing arterial blood flow by simulation of bifurcation trees
Master-uppsats, Linköpings universitet/Matematik och tillämpad matematikSammanfattning : The flow of blood in the human body is a very important component in un-derstanding a number of different ailments such as atherosclerosis and a falseaneurysm. In this thesis, we have utilized Poiseuille’s solution to Navier-Stokesequations with a Newtonian, incompressible fluid flowing laminar with zero ac-celeration in a pipe with non-flexible walls in order to study blood flow in anarterial tree.
