The Einstein and the Navier-Stokes Equations: Connecting the Two
(2013-02-22)This thesis establishes a precise mathematical connection between the Einstein equations of general relativity and the incompressible Navier-Stokes equation of fluid dynamics. We carry out a holographic analysis which ... -
Escaping the flow: boundary layer use by the darter Etheostoma tetrazonum (Percidae) during benthic station holding
(The Company of Biologists, 2011)Aquatic habitats characterized by directional water flow (lotic environments) pose numerous challenges to their inhabitants, including the constant threat of dislodgement and downstream transport. As a result, many organisms ... -
The hydrodynamics of eel swimming: I. Wake structure
(The Company of Biologists, 2004)Eels undulate a larger portion of their bodies while swimming than many other fishes, but the hydrodynamic consequences of this swimming mode are poorly understood. In this study, we examine in detail the hydrodynamics of ... -
Hydrodynamics of the escape response in bluegill sunfish, Lepomis macrochirus
(The Company of Biologists, 2008)Escape responses of fishes are one of the best characterized vertebrate behaviors, with extensive previous research on both the neural control and biomechanics of startle response performance. However, very little is known ... -
Modeling Cardiovascular Hemodynamics Using the Lattice Boltzmann Method on Massively Parallel Supercomputers
(2013-09-23)Accurate and reliable modeling of cardiovascular hemodynamics has the potential to improve understanding of the localization and progression of heart diseases, which are currently the most common cause of death in Western ... -
Non-invasive measurement of instantaneous forces during aquatic locomotion: a case study of the bluegill sunfish pectoral fin
(The Company of Biologists, 2007)Swimming and flying animals generate unsteady locomotive forces by delivering net momentum into the fluid wake. Hence, swimming and flying forces can be quantified by measuring the momentum of animal wakes. A recently ... -
Performance Analysis of the Lattice Boltzmann Model Beyond Navier-Stokes
(Institute of Electrical and Electronic Engineers, 2013)The lattice Boltzmann method is increasingly important in facilitating large-scale fluid dynamics simulations. To date, these simulations have been built on discretized velocity models of up to 27 neighbors. Recent work has ... -
Population Dynamics at High Reynolds Number
(American Physical Society, 2010)We study the statistical properties of population dynamics evolving in a realistic two-dimensional compressible turbulent velocity field. We show that the interplay between turbulent dynamics and population growth and ... -
Quantifying Patterns of Morphological Diversity
(2013-10-18)One of the central questions of biology is how shape is formed by the interaction
