1. PIV in Practice
Sammanfattning : Experimental fluid mechanics has for a long time been used to visualize flow phenomenonqualitatively. Traditionally, visualization has been done with dye or tracer particle dueto their ability to follow the flow pattern well. LÄS MER
2. Large Eddy Simulation of Turbulent Swirling Flows in Combustor Related Geometries
Sammanfattning : This thesis deals with the physics of turbulent swirling flows. Large eddy simulation (LES) method is used to investigate the vortex breakdown process, the precessing vortex core (PVC), and the effect of swirl number and flow field configuration on swirling flows. The study is based on an open source CFD code, \textit{OpenFoam}. LÄS MER
3. Hydrodynamics in a stirred square tank investigated using PIV and LDA measurements
Sammanfattning : .... LÄS MER
4. Particle image velocimetry in practice
Sammanfattning : Experimental fluid mechanics has for a long time been used to visualize flow phenomenon. An early pioneer was Ludwig Prandtl who used aluminum particles in water flumes to describe the flow in a qualitative manner. In line with the rapid development of Computational Fluid Dynamics, CFD, the need for new validation tools has increased. LÄS MER
