A technique for determining viable military logistics support alternatives
(Georgia Institute of Technology, 2009-03-05)
A look at today's US military will see them operating much beyond the scope of protecting and defending the United States. These operations now consist of, but are not limited to humanitarian aid, disaster relief, and ...
Wall-models for large eddy simulation based on a generic additive-filter formulation
(Georgia Institute of Technology, 2008-12-19)
In this work, the mathematical implications of merging two different turbulence modeling approaches are addressed by deriving the exact hybrid RANS/LES Navier-Stokes equations. These equations are derived by introducing ...
A small perturbation based optimization approach for the frequency placement of high aspect ratio wings
(Georgia Institute of Technology, 2009-03-26)
Design denotes the transformation of an identified need to its physical embodiment in a traditionally iterative approach of trial and error. Conceptual design plays a prominent role but an almost infinite number of possible ...
Study of compressible turbulent flows in supersonic environment by large-eddy simulation
(Georgia Institute of Technology, 2009-02-19)
A Large-Eddy Simulation (LES) methodology adapted to the resolution of high Reynolds number turbulent flows in supersonic conditions was proposed and developed. A novel numerical scheme was designed, that switches from a ...
A Design Space Exploration Process for Large Scale, Multi-Objective Computer Simulations
(Georgia Institute of Technology, 2006-07-07)
The primary contributions of this thesis are associated with the development of a new method for exploring the relationships between inputs and outputs for large scale computer simulations. Primarily, the proposed design ...
A Systematic Process for Adaptive Concept Exploration
(Georgia Institute of Technology, 2006-11-29)
This thesis presents a method for streamlining the process of obtaining and interpreting quantitative data for the purpose of creating a low-fidelity modeling and simulation environment. By providing a more efficient means ...
Large eddy simulation of premixed and non-premixed combustion in a stagnation point reverse flow combustor
(Georgia Institute of Technology, 2008-03-10)
A new combustor, referred to as Stagnation Point Reverse Flow (SPRF) combustor has been developed at Georgia Tech to meet increasingly stringent emission regulations. The combustor incorporates a novel design to meet the ...
An integrated approach to the design of supercavitating underwater vehicles
(Georgia Institute of Technology, 2007-05-09)
A supercavitating vehicle, a next-generation underwater vehicle capable of changing the paradigm of modern marine warfare, exploits supercavitation as a means to reduce drag and achieve extremely high submerged speeds. ...
Scaling of turbulence and turbulent mixing using Terascale numerical simulations
(Georgia Institute of Technology, 2007-08-09)
Fundamental aspects of turbulence and turbulent mixing are investigated using direct numerical simulations (DNS) of stationary isotropic turbulence, with Taylor-scale Reynolds numbers ranging from 8 to 650 and Schmidt ...
Distributed uncertainty analysis techniques for conceptual launch vehicle design
