Analysis of hydrodynamic phenomena in a fluidized bed for thermochemical hydrogen production
This thesis examines transport phenomena of cupric chloride (CuCI2) hydrolysis within a fluidized bed. Conversions of CuCi2 and steam as a fluidizing gas are numerically investigated using a new non-catalytic gas-solid reaction model, proposed in the literature but here updated for the purposes of …

Incorporating thruster dynamics in the control of an underwater vehicle
… may permit on-line adaptation to complex hydrodynamic phenomena associated with complete vehicle/thruster configurations such as cross-flow and mutual interference.

Análise dos fenômenos transitórios em câmaras de eclusas através do método das características bi-dimensional
… during filling or emptying procedures. The hydrodynamic phenomena are caused by unsteady filling and were studied considering the chamber’s two horizontal directions. The solution was obtained using the Method of Characteristics. Two theorical examples of filling were developed and their …

Thermal transport at the nanoscale : from fourier diffusion to phonon hydrodynamics
… develop a formalism to study size effects and hydrodynamic phenomena by solving the full scattering matrix version of the linearized Boltzmann transport equation. Using this formalism as a guide, we report the experimental observation of second sound in graphite.

Hybrid atomistic-continuum formulations for gaseous flows
… formulations allow the simulation of complex hydrodynamic phenomena at the nano and micro scales without the prohibitive cost of a fully atomistic approach. This is achieved through a domain decomposition strategy whereby the atomistic model is limited to regions of the flow field where …

Protein folding and diffusion: from in vitro to live cells
… hydrophobic interactions, and even hydrodynamic phenomena. The resulting spatio-temporal fluctuations in protein folding rates, protein stability, protein diffusion, as well as protein structure, protein function, and protein interactions are the subject of a recent generation of …

High voltage repetitive pulsed nanosecond discharges as a selective source of reactive species
… during the interval between pulses and the hydrodynamic phenomena triggered by the rapid energy deposition need clarification. This work seeks to be an introductory text to the field of nanosecond duration non-thermal discharges and prepare the building blocks to initiate discharge …

Design and implementation of an ocean observing system: WAVCIS (Wave-Current-Surge Information System) and its application to the Louisiana coast
… was designed to measure meteorological and hydrodynamic phenomena along the Louisiana coast. The information measured includes waves, currents, water depth, surge, turbidity, salinity and meteorological conditions. WAVCIS collects data and transfers it back to the data processing laboratory …

A study of liquid-liquid extraction in a sieve plate column
… plate liquid extraction columns and relevant hydrodynamic phenomena have been surveyed. Mass transfer characteristics during drop formation, rise and coalescence, and related models were also reviewed. Important design parameters i.e. flooding, dispersed phase hold-up, drop size distribution, …

Electron Hydrodynamics in Crystalline Solids: Microscopic Origins, Mesoscopic Size Effects, and Macroscopic Observables
… example of emergent transport phenomena with distinct spatial signatures is the recently re-invigorated field of “electron hydrodynamics”. Advances in spatially-resolved transport measurements have revealed that electrons in condensed matter can flow collectively, exhibiting …

Towards an understanding of mass transfer and hydrodynamics in packed bed reactors using Nuclear Magnetic Resonance
… (NMR) techniques to study mass transfer and hydrodynamic phenomena that govern the performance of packed bed reactors. The aim of this work is to gain insight into factors that affect the process of fines deposition and mass transfer inside packed beds to ultimately enable optimisation of …
