Spring 2010
We report upon an experimental study of internal gravity waves generated by the large-amplitude vertical oscillations of a circular cylinder in uniformly stratified fluid. Quantitative measurements are performed using a modified synthetic schlieren technique for strongly stratified solutions of...

Improved Quantification of Viscoelastic Effects during Polymer Flooding Using Extensional Rheology
DownloadSpring 2019
Polymer flooding is one of the traditional chemical enhanced oil recovery (EOR) methods with a high rate of success. Synthetic polymer such as hydrolyzed polyacrylamide (HPAM) characterized by flexible chain exhibits viscoelastic characteristics in porous media. Some of the implications of the...

Internal gravity waves transport energy and momentum in both the atmosphere and the ocean. This physical process occurs at such small length scales that it is not captured by coarse resolution numerical models of weather and climate. A series of experiments is presented that model the generation...

Turbulence is a chaotic motion of fluid that can be described by the Navier--Stokes equations or even highly simplified shell models. Under the continuum limit, standard shell models of turbulence are shown to reduce to a common evolution equation that reproduces many predictions of the...

As internal tides propagate in the ocean, they carry and dissipate energy over hundreds and even thousands of kilometers. We perform fully nonlinear simulations to examine the evolution of horizontally propagating, vertical mode-1 internal tides in non-uniformly stratified fluids, as it depends...

Numerical Simulations of Anelastic and Boussinesq Rotating Convection with Radial Entropy Gradient Boundary Conditions
DownloadFall 2017
Observations from the gas giants Jupiter or Saturn allow for researchers to construct geophysical fluid dynamical numerical models in an attempt to replicate the observed features. Most models aim at replicating the zonal jets and the eddies observed on these gas giants to understand how they are...

Optimization of Drilling Fluid Rheological Properties for Improved Cuttings Transport and Dynamic Filtration Loss Control Performance: A Comparative Study of the Fluid Viscoelasticity versus the Shear Viscosity Effects
DownloadFall 2022
Recent studies highlighted the significant role of drilling fluid viscoelasticity in the assessment of frictional pressure loss, particle settling velocity, hole cleaning efficiency, and dynamic filtration loss control. Although the impact of drilling fluid viscoelasticity on the various...
