Dynamic modeling, simulation and stability analysis of brushless doubly-fed machines

Creator:: Li, Ruqi
Abstract:: A brushless doubly-fed machine (BDFM) is a single-frame, self-cascaded induction machine capable of operating in both the induction and the synchronous modes. This thesis presents some important advances concerning dynamic modeling, simulation and analysis of the BDFM. Initially, a two-axis model and its associated parameters are developed and calculated. The...

Modeling a heat regenerator-reactor with temperature dependent gas properties

Creator:: Kulkarni, Milind S.
Abstract:: This thesis examines the transient response of a packed bed heat regenerator when heated from an initial uniform bed temperature. Very large (1700 K) temperature differences were studied as well as the effect of simultaneous chemical reaction in the gas phase. First the effects of temperature on physical and transport...

Identification of structural parameters and hydrodynamic effects for forced and free vibration

Creator:: Kruchoski, Brian L. (Brian Louis)
Abstract:: Statistically-based estimation techniques are presented in this study. These techniques incorporate structural test data to improve finite element models used for dynamic analysis. Methods are developed to identify optimum values of the parameters of finite element models describing structures. The parameters which may be identified are : element area, mass...

Modelling, validation and simulation of multi-degree-of-freedom nonlinear stochastic barge motions

Creator:: Bartel, Warren A.
Abstract:: Recent developments in estimation of the survivability of a U.S. Navy transport barge in random seas are extended to improve accuracy. The single Degree-of-Freedom (DOF) model of a extreme roll response of a barge used in previous research is replaced by a 3-DOF roll-heave-sway model to include linear and nonlinear...

The hydrodynamic theory of mass transport and matter forces of water

Creator:: Ali, Abdulmuhsen H.
Abstract:: In chapter 3 of our paper we present equations of motion for continuous mass distribution subject to hydrodynamic forces in their most general form. We start with equations for discrete mass particles and then transform the equations so that it is appropriate for a continuous mass distribution. As we do...

A kinetic model for dissolved gas transport in the presence of trapped gas

Creator:: Donaldson, Jeremy H.
Abstract:: Understanding the processes involved in the transport of dissolved gas plumes in groundwater aquifers is essential for comprehending the effect that these transport processes can have on site characterization and remedial design applications. Previous laboratory and field studies have indicated that dissolved gas transport in groundwater can be greatly affected...

Winter cover cropping effects on integrative biological indicators of soil quality

Creator:: Ndiaye, Evelyne L.
Abstract:: Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...
