A novel lattice Boltzmann method for treatment of multicomponent convection, diffusion, and reaction phenomena in multiphase systems

Creator:: Parker, James Muirhead
Abstract:: In this work, a multicomponent lattice Boltzmann model is developed for the simulation of multiphase mixing, reactions, and separations processes. This model is unique in that diffusive mass transfer of a component in the model is driven by gradients of chemical potential. This fundamentally correct description of diffusion accurately captures...

A numerical model of drop-on demand droplet formation from a vibrating nozzle and a rigid nozzle

Creator:: Yang, Guozhong
Abstract:: Droplet formation from a rigid and a vibration nozzle driven by a pulsing pressure is simulated. Droplet formation is simulated by using one-dimensional model. For the case of droplet formation from a vibration nozzle, the nozzle vibration is simulated by large deflection plate vibration equation. Droplet formation from a rigid...

A numerical study of inertial flow features in moderate Reynolds number flow through packed beds of spheres

Creator:: Finn, Justin Richard
Abstract:: In this work, flow through synthetic arrangements of contacting spheres is studied as a model problem for porous media and packed bed type flows. Direct numerical simulations are performed for moderate pore Reynolds numbers in the range, 10 ≤ Re ≤ 600, where non-linear porescale flow features are known to...

A numerical study of viscous, incompressible fluid flow problems

Creator:: Terry, Michael D.
Abstract:: The mathematical technique of overrelaxation is used here to speed the convergence of a numerical method for solving viscous, incompressible fluid flow problems. The method, called MAC, involves approximating the complete two-dimensional incompressible Navier-Stokes equations with analogous finite-difference equations. The MAC method was developed by the Los Alamos Scientific Laboratory...

A study of El Niño/southern oscillation : numerical experiments and data analysis

Creator:: Ahn, Joong Bae
Abstract:: For the purpose of investigating the fundamental nature of the interannual oscillation observed in the tropical Pacific in conjunction with El Nino/Southern Oscillation (ENSO), the Comprehensive Ocean Atmosphere Data Set was analyzed. Based upon this analysis, an "intermediate" tropical atmosphere-ocean coupled model was developed. For reason of their particular importance...

An analysis of wave forces on prototype walls under tsunami loading

Creator:: Oshnack, Mary Elizabeth
Abstract:: This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...

An approach to reduced-order modeling and feedback control for wave energy converters

Creator:: Shoori J., Hesam E.
Abstract:: Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...

An empirical statistical model relating winds and ocean surface currents : implications for short-term current forecasts

Creator:: Zelenke, Brian Christopher
Abstract:: An empirical statistical model is developed that relates the non-tidal motion of the ocean surface currents off the Oregon coast to forecasts of the coastal winds. The empirical statistical model is then used to produce predictions of the surface currents that are evaluated for their agreement with measured currents. Measurements...

An experimental flow model of a centifugal casting system

Creator:: Sewell, Janet M.
Abstract:: Centrifugal casting has been a successful technique for quickly filling molds, but little is understood about the fluid flow characteristics that occur during filling. The understanding of these flow characteristics and the application of this knowledge should improve the quality of metal parts cast by this process. The subject of...
