2016/5/18
Direct numerical simulations of scalar fields produced by uniform and line sources in channel flow are used as the basis for examining the accuracy of random flight and closure models in predicting tu...
Theorists smooth the way to modeling quantum friction
Theorists smooth the way quantum friction
2016/5/19
Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle’s environment drags on it, a vexing problem in quantum mechanics since the birth...
Factor of safety in a partially saturated slope inferred from hydro-mechanical continuum modeling
partially saturated soil hydromechanical model slope stability
2015/7/1
Rainfall weakens an earth slope and triggers mass movement. Relevant triggering mechanisms are complex and include reduction of capillary pressure due to increased saturation and frictional drag on th...

Continuum mathematical modeling slip weakening geological systems
2015/7/1
Deformation of the Earth’s crust from tectonic forces involves both diffuse elastic and plastic strains, rigid body translations and rotations, and localized deformations concentrated along narrow fau...

Modeling deformation banding dense and loose fluid-saturated sands
2015/7/1
Balance of mass and linear momentum of a solid–fluid mixture furnish a complete set of equations from which the displacements of the solid matrix and the pore pressures can be resolved for the case of...
Modeling the tidal and sub-tidal hydrodynamics in a shallow, micro-tidal estuary

2015/6/30
The three-dimensional hydrodynamics of Galveston Bay were simulated in two periods of several month duration. The physical setting of Galveston Bay is described by synthesis of long-term observations....
Analytical modeling for the heat transfer in sheared flows of nanofluids
Analytical modeling heat transfer sheared flows of nanofluids Fluid Dynamics
2012/4/24
We developed a model for the enhancement of the heat flux by spherical and elongated nano- particles in sheared laminar flows of nano-fluids. Besides the heat flux carried by the nanoparticles the mod...
We present a method to construct random model power grids that closely match statistical properties of a real power grid. The model grids are more difficult to partition than a real grid.
Surrogate-based modeling and dimension reduction techniques for multi-scale mechanics problems
Multi-scale mechanics Cryogenic cavitating flow Surrogate-based modeling Active flow control Engineering system
2012/2/28
Successful modeling and/or design of engineering systems often requires one to address the impact of multiple “design variables” on the prescribed outcome. There are often multiple, competing objectiv...
Implementing and assessing computational modeling in introductory mechanics
Research in Physics Education Curricula and evaluation Teaching methods and strategies
2011/8/11
Abstract: Students taking introductory physics are rarely exposed to computational modeling. In a one-semester large lecture introductory calculus-based mechanics course at Georgia Tech, students lear...
Modeling the transition to turbulence in shear flows
Modeling transition turbulence shear flows
2011/8/5
Abstract: One-dimensional models are presented for transitional shear flows. The models have two variables corresponding to turbulence intensity and mean shear. These variables evolve according to sim...
