CFD study of diffuser geometry effects on diffuser augmented wind turbine performance
This thesis aims to explore the performance limits of diffuser augmented wind turbines. Many studies of this topic have been performed in the past. Limiting assumptions and manufacturing concerns have forced the majority of previous studies to stray away from finding optimal performance in favor of …

Actuator Disk Theory for Compressible Flow
… flow. As the free-stream Mach increases, the Betz limit of the compressible bare turbine slightly increases from the incompressible value of 0.593 and occurs at a velocity ratio between the far downstream and the free-stream that is lower than the incompressible value of 0.333. From …

Numerical Modeling and Optimization of Power Generation from Shrouded Wind Turbines
… of a wind turbine can be increased beyond the Betz limit for a bare turbine by enclosing the turbine with a duct. In this thesis, this potential for increases in power generation by adding a shroud around a turbine is investigated using numerical flow modeling. Two configurations for ducted …
