1. 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
2. On Turbulence Modelling for Bilge Vortices: A Test of Eight Models for Three Cases
Sammanfattning : This work is a test, in three steps, of turbulence models for the calculation of the flow field around ships. Eight models ranging from k-e and k-w models to a Reynolds-stress model (RSM) are tested. LÄS MER
3. Nonlinear dynamics of strongly-bound magnetic vortex pairs
Sammanfattning : This work is a study of nonlinear phenomena in vertically stacked pairs of magnetic vortices. New dynamic regimes are uncovered with a decrease in the inter-vortex separation to below the lateral vortex-core size. LÄS MER
4. Transport barriers in plasmas and fluids
Sammanfattning : .... LÄS MER
5. Large Eddy Simulation of Turbulent Swirling Flows and Turbulent Premixed Combustion
Sammanfattning : With the increasing concerns about our environment and human health, more and more stringent emission limits have been specified. These adopted and still coming emission limits require and promote more accurate, less experiential methods to design and develop the combustors. LÄS MER
