45. Virtual Permeametry on Microtomographic Images
Published: 11/1/2004
Authors: C H Arns, M A Knackstedt, W V Pinczewski, Nicos Martys
Abstract: We show that accurate numerical micropermeametry measurements can be performed on three dimensional digitized images of sedimentary rock. The sample size can be very small making it possible to predict properties from core material not suited for l ...

46. Breakup of a Fluid Thread in a Confined Geometry: Droplet-Plug Transition Perturbation Sensitivity and Kinetic Stabilization with Confinement
Published: 5/26/2004
Authors: John G Hagedorn, Nicos Martys, Jack F Douglas
Abstract: The breakup of a fluid thread surrounded by another Newtonian fluid in a coaxial tube in the absence of imposed flow is investigated using the Lattice Boltzmann (LB) model. We observe a confinement-induced transition between spherical droplets to p ...

47. Breakup of a Fluid Thread in a Confined Geometry: Droplet-Plug Transition Perturbation Sensitivity and Kinetic Stabilization With Confinement .
Published: 5/1/2004
Authors: John G Hagedorn, Nicos Martys, J. F. Douglas
Abstract: We investigate the influence of geometrical confinement on the breakup of long fluid threads in the absence of imposed flow using a lattice Boltzmann model. Our simulations primarily focus on the case of threads centered coaxially in a tube filled wi ...

48. The Rheology of Cementitious Materials: Chemistry, Colloids and Rocks
Published: 5/1/2004
Authors: Robert J Flatt, Nicos Martys
Abstract: Knowledge of colloidal science has proven essential in the development of a new generation of dispersants for concrete. These polymer molecules induce steric repulsion between cement particles, reducing agglomeration and allow high workability to b ...

49. Simulation of Sheared Suspensions With a Parallel Implementation of Quaternion-Based Dissipative Particle Dynamics (QDPD)
Series: Journal of Research (NIST JRES)
Published: 4/1/2004
Authors: James S Sims, Nicos Martys
Abstract: A quaternion-based dissipative particle dynamics (QDPD) program was developed to study the flow properties of complex fluids like suspensions, subject to shear. To overcome CPU speeds limiting the size and complexity of the simulations that can be ca ...
