Ion Solvation in Water Acetonitrile Mixtures

January 1, 2001
Author(s)
Raymond D. Mountain
The results of a preliminary molecular dynamics study of ion (NA+ and Cl-) solvation and association in water, acetonitrile, and aqueous acetonitrile are discussed. These mixtures are compositionally heterogeneous on the scale of a few molecular sizes, and

Issues Related to Spray Combustion Modeling Validation

January 1, 2001
Author(s)
J F. Widmann, Cary Presser
Validation of CFD predictions for spray combustion application has been a challenging task due to difficulties in both modeling and experimental measurements. However, validation is considered to be an essential exercise for the success of CFD tools in the

Kinematic Modeling and Analysis of a Planar Micro-Positioner

January 1, 2001
Author(s)
Nicholas G. Dagalakis, John A. Kramar, E Amatucci, Robert Bunch
The static and dynamic performance of a control system depends on the accuracy of the mathematical model of the plant that is being controlled. In this work, the accuracies of a linear and a second-order kinematic model were evaluated for a two-dimensional

Kinetics of Reactions of H Atoms With Methane and Chlorinated Methanes

January 1, 2001
Author(s)
M G. Bryukov, I R. Slagle, Vadim D. Knyazev
The reactions of H atoms with methane, four chlorinated methanes, and isobutene have been studied experimentally using the Discharge Flow / Resonance Fluorescence technique over wide ranges of temperatures. The rate constants were obtained in direct

Large-Area TKIDs for a New Generation of Neutron Beta Decay Experiments

January 1, 2001
Author(s)
Elizabeth Scott, Jimmy P. Caylor, Maynard S. Dewey, Jiansong Gao, Colin A. Heikes, Shannon Hoogerheide, Hans Pieter Mumm, Jeffrey S. Nico, Joel Ullom, Michael Vissers
Nuclear physics has long played a central role in our efforts to better understand the natural world. Several experiments are well positioned to improve limits in searches for physics Beyond the Standard Model (BSM). Many of the experiments in nuclear
