1. Vortex Properties from Resistive Transport Measurements on Extreme Type-II Superconductors
Sammanfattning : .... LÄS MER
2. Wind turbine wakes : controland vortex shedding
Sammanfattning : Wind tunnel studies of the wake behind a model wind turbine have been made in order to get a better understanding of wake development as well as the possibility to predict the power output from downstream turbines working in the wake of an upstream one. Both two-component hot-wire anemometry as well as particle image velocimetry (PIV) have been used to map the flow field. LÄS MER
3. Vortex fluctuations in superconductors
Sammanfattning : The vortex fluctuations have proved to be responsible for the onset of dissipation in thin type-II superconducting Aims. There is also growing evidence that dissipation in high- temperature superconductors exhibits the same kind of two-dimensional (2D) behavior. LÄS MER
4. Analytical vortex solutions to Navier-Stokes equation
Sammanfattning : Fluid dynamics considers the physics of liquids and gases. This is a branch of classical physics and is totally based on Newton's laws of motion. Nevertheless, the equation of fluid motion, Navier-Stokes equation, becomes very complicated to solve even for very simple configurations. LÄS MER
5. On the three-dimensionality of vortex shedding from a circular cylinder
