Fluid dynamics in action
… effective field theory for nonlinear dissipative fluid dynamics. The formalism incorporates an action principle for the classical equations of motion as well as a systematic approach to thermal and quantum fluctuations around the classical motion of fluids. The dynamical degrees of freedom are …

Nontraditional approximation in geophysical fluid dynamics
In the conventional approach to geophysical fluid dynamics, only the horizontal components of the Coriolis force due to horizontal motions of the fluid are taken into account. All the other components of the Coriolis force, which are called the non-traditional (NT) terms, are considered to be small …

Fluid dynamics of boundary layer combustion
… layer, representing a marriage of thermal, fluid, and combustion sciences, have been studied for decades by the scientific community. However, the role of coherent structures within the three-dimensional flow field is largely untouched. In particular, little knowledge exists regarding …

Interfacial Fluid Dynamics in Porous Media
A beautiful array of patterns emerges when one fluid displaces another in porous media, a physical situation prevalent in many clean energy production and storage applications. These patterns can be reminiscent of dielectric breakdown, diffusion-limited growth of crystals, or percolation clusters …

Fluid dynamics of biological and mechanical olfaction
… olfaction. In this dissertation, we focus on the fluid mechanics of olfaction. We used a combined experimental and theoretical approach, with particular emphasis on building machines that can mimic the olfaction of animals. We show that many animals have a hierarchical structure to their olfaction …

Fluid Dynamics Characterization of Transcatheter Aortic Valves
… (TAVs) have limited clinical data in term of fluid dynamics performance of TAVs, in contrast to surgical aortic valves (SAVs). Due to limitations associated with devices that are used to evaluate the performance of TAVs in patients such as echocardiography, magnetic response imaging (MRI) and …

Fluid Dynamics Simulations on Multi-GPU Systems
… and testing of the multi-GPU version of two fluid flow simulation models, focusing on the cellular automaton MAGFLOW lava flow simulator and the GPU-SPH model for Navier-Stokes. In both cases, a spatial subdivision of the domain is performed, with a minimal overlap to ensure the correct …

An action principle for dissipative fluid dynamics
Fluid dynamics is the universal theory of low-energy excitations around equilibrium states, governing the physics of long-lived modes associated with conserved charges. Historically, fluid dynamics has been formulated at the level of equations of motion, in terms of a local fluid velocity and …

Fluid Dynamics in Liquid Entry and Exit
… there are no existing previous studies on the dynamics of the contact line on a sinking object. This subject will be first discussed in Chapter 2. In Chapters 3 and 4, the topics related to liquid-exit will be discussed, where a solid sphere exits out of a liquid toward air with constant …

Unsteady Viscous Cavity Flow Using Computational Fluid Dynamics
<p>The problem of unsteady viscous incompressible flow in a two-dimensional cavity is treated using the unsteady incompressible Navier-Stokes equations with various initial and boundary conditions. First the case of a square cavity with one inlet and one outlet is treated in steady and unsteady …

The Effective Field Theory Approach to Fluid Dynamics
In this thesis we initiate a systematic study of fluid dynamics using the effective field theory (EFT) program. We consider the canonical quantization of an ordinary fluid in an attempt to discover if there is some kind of quantum mechanical inconsistency with ordinary fluids at zero temperature. …
