A time-domain model was developed to predict the fluid/structure
interaction of a three-dimensional deformable body in a fluid domain subject to
long-crested finite amplitude waves. These nonlinear waves induce transient
motion in the body. In turn, the interaction of the body with the waves modifies
the wave field, causing additional...
Time-domain models were developed to predict the response of a tethered buoy
subject to hydrodynamic loadings. A coupled analysis of the interaction of a buoy and
its mooring is included and three-dimensional response is assumed. External loadings
include hydrodynamic forces, tethers tensions, wind loadings and the weight of both
cable...
This thesis investigates the effects of wave energy converters (WECs) on water waves through the analysis of extensive laboratory experiments, as well as subsequent numerical simulations. Data for the analysis was collected during the WEC-Array Experiments performed at the O.H. Hinsdale Wave Research Laboratory at Oregon State University, under co-operation...
Incipient motion of cohesive sediment and the role of flow
parameters were investigated for separate and combined unidirectional
and oscillatory flows. Sediment from Sturgeon Lake, mainly silt and
clay with organic matter, was used as bed material In recirculating
and wave flumes.
Bench-type experiments indicated that when the submerged sediment...
The success of civil engineering construction in cold regions often depends on the
assessment of the potential for frost heave. Over the past two decades two models have
been presented to the engineering community to identify the frost heave potential,
namely: (1) the segregation potential (SP), and (2) the discrete...
Studies were conducted on the mechanisms contributing to
resistance in broccoli, Brassica oleracea italica, to the garden
symphylan, Scutigerella immaculata (Newport). Differences in
resistance to symphylan injury were shown between five selected
broccoli cultivars. The hybrid cultivars, Crusader, Green Duke
and Bravo, showed a higher level of resistance to symphylans...
This thesis presents a feasibility study of a thorium fueled thermal spectrum breeder-burner reactor that operates without chemical reprocessing. Materials were evaluated for their potential as moderators using standard analytical methods. These materials were then used as moderators to evaluate criticality and enrichment in an infinite fuel pin lattice. The...
