Automated Cfd Optimization To Maximize Wind Farms Performance And Land Use, Rafael Valotta Rodrigues
Electronic Theses and Dissertations
In this research, a computational system was designed to analyze and optimize the layout of wind farms under variable operational conditions. At first, a wind turbine computational fluid dynamic (CFD) model was developed covering the near wake. The near wake flow field was validated against near wake velocity data from the MEXICO experiment. The CFD simulation demonstrated that the tip speed ratio and the pitch angle greatly influence the near wake behavior, affecting the velocity deficit and the turbulence intensity profile in this region. The CFD model was extended to cover the far wake, aiming to become a computational tool …

Computational Fluid Dynamics (Cfd) Modeling Of A Laboratory Scale Coal Gasifier, Kiel S. Schultheiss
Electronic Theses and Dissertations
Furthering gasification technology is an essential part of advancing clean coal technologies. In order to seek insight into the appropriate operations for the formation of synthetic gas (syngas) a numerical simulation was performed to predict the phenomena of coal gasification in a laboratory scale entrained-flow coal gasifier. The mesh for the model was developed with ICEM CFD software and the chemical and physical phenomena were modeled using the fluid flow solver ANSYS FLUENT. Mesh independence was verified. The model was validated with experimental data from several studies performed on a laboratory scale gasifier.
Systematic examination of the model was performed …

Modeling Of Growth Kinetics And Characterization Of Membrane Mechanics, Antonio Nava
Electronic Theses and Dissertations
One growing field in alternative energy is biofuel production through microorganisms. These fields of research include hydrogen and biofuel production through the cultivation of algae. We've selected 2 different algae, Anabaena sp. cpcc 387 and Tetraselmis to study. Through mathematical modeling of Anabaena we investigate the complex multicellular relationships and colony stability when noise is introduced. In conjunction with researchers at NREL, we've set out to characterize Tetraselmis cells' membrane elasticity.
