16. Wind turbine simulations using spectral elements
Sammanfattning : Understanding the flow around wind turbines is a highly relevant research question due to the increased interest in harvesting energy from renewable sources. This thesis approaches the topic by means of numerical simulations using the actuator line method and the incompressible Navier–Stokes equations in the spectral element code Nek5000. LÄS MER
17. Wind-turbine wakes - Effects of yaw, shear and turbine interaction
Sammanfattning : The actuator-line method is used together with the incompressible Navier–Stokes equations to investigate the flow development behind wind turbines. Initial investigations focus on providing a thorough validation of the implementation in the spectral-element flow solver Nek5000 against existing numerical and experimental datasets. LÄS MER
18. Approaching Large Eddy Simulation of Cavitating Flows for Marine Applications
Sammanfattning : Cavitation is a major concern in naval craft design as well as in the shipping industry. Although the nature of cavitation is not fully understood, propellerdesigns are presently improved by experimental analysis of the phenomena. LÄS MER
19. Numerical Methods for Fluid Interface Problems
Sammanfattning : This thesis concerns numerical techniques for two phase flowsimulations; the two phases are immiscible and incompressible fluids. Strategies for accurate simulations are suggested. LÄS MER
20. Experimental and Mathematical Study of Incompressible Fluid Flow through Ceramic Foam Filters
Sammanfattning : Ceramic Foam Filters (CFFs) are widely used to filter solid particles and inclusions from molten metal in metal production, particularly in the aluminum industry. In general, the molten metal is poured on the top of a ceramic foam filter until it reaches a certain height, also known as metal head or gravity head. LÄS MER
