Three-Dimensional Free Surface Non-Hydrostatic Modeling Of Plunging Water With Turbulence And Air Entrained Transport, Tien Mun Yee
Three-Dimensional Free Surface Non-Hydrostatic Modeling Of Plunging Water With Turbulence And Air Entrained Transport, Tien Mun Yee
University of Kentucky Doctoral Dissertations
The advance in computational fluid dynamics in recent years has provided the opportunity for many fluid dynamic problems to be analyzed numerically. One such problem concerns the modeling of plunging water into a still water body, often encountered in pump stations. Air bubbles introduced into the system by the plunging jet can be a significant problem, especially when consumed into operating pumps. The classical approach to investigate the hydrodynamics of plunging jet in pump stations is by physical model studies. This approach is time consuming, tedious and costly. The availability of computational power today, along with appropriate numerical techniques, allows …

Analytical Strip Method To Antisymmetric Laminated Plates, Liecheng Sun
University of Kentucky Doctoral Dissertations
An Analytical Strip Method (ASM) for the analysis of stiffened and non-stiffened antisymmetric laminated composite plates is derived by considering the bending-extension coupling effect for bending, free vibration and buckling. A system of three equations of equilibrium, governing the general response of arbitrarily laminated composite plates, is reduced to a single eighth order partial differential equation in terms of a displacement function. The displacement function is solved in a single series form to determine the displacement, fundamental frequency, and buckling load of antisymmetric cross-ply and angle-ply laminated composite plates. The solution is applicable to rectangular plates with two opposite edges …

Vortex Model Of Open Channel Flows With Gravel Beds, Brian James Belcher
University of Kentucky Doctoral Dissertations
Turbulent structures are known to be important physical processes in gravel-bed rivers. A number of limitations exist that prohibit the advancement and prediction of turbulence structures for optimization of civil infrastructure, biological habitats and sediment transport in gravel-bed rivers. This includes measurement limitations that prohibit characterization of size and strength of turbulent structures in the riverine environment for different case studies as well as traditional numerical modeling limitations that prohibit modeling and prediction of turbulent structure for heterogeneous beds under high Reynolds number flows using the Navier-Stokes equations. While these limitations exist, researchers have developed various theories for the structure …
Investigation Of Surface Fine Grained Laminae, Streambed, And Streambank Processes Using A Watershed Scale Hydrologic And Sediment Transport Model, Joseph Paul Russo
Investigation Of Surface Fine Grained Laminae, Streambed, And Streambank Processes Using A Watershed Scale Hydrologic And Sediment Transport Model, Joseph Paul Russo
University of Kentucky Doctoral Dissertations
Sediment transport at the watershed scale in the Bluegrass Region of Kentucky is dominated by surface fine grained laminae, streambed, and streambank erosion; high instream sediment storage; and surface erosion processes. All these processes can be impacted by agricultural, urban, and suburban land-uses as well as hydrologic forcing. Understanding sediment transport processes at the watershed scale is a need for budgeting and controlling sediment pollution, and watershed modeling enables investigation of the cumulative effect of sediment processes and the parameters controlling these processes upon the entire sediment budget for a watershed. Sediment transport is being modeled by coupling the hydrologic …
