Reducing Uncertainty in Particle Size Measurement for Liquid Filter Testing

January 1, 2006
Author(s)
Barry M. Verdegan, Robert A. Fletcher
Contamination control is essential to reliable, cost-effective operation of hydraulic and engine systems. Particle counting provides the common, underlying basis for comparing filter performance and monitoring of contamination levels in hydraulic oil, lube

Relaxation Effects in Small Critical Nozzles

January 1, 2006
Author(s)
Aaron N. Johnson, C L. Merkle, Michael R. Moldover, John D. Wright
We computed the flow of four gases (He, N 2, CO 2, and SF 6) through a critical nozzle by augmenting traditional computational fluid dynamics (CFD) with a rate equation that accounts for τ relax, a species-dependent relaxation time that characterizes the

Rheo-Optic Studies of Carbon Nanotube Suspensions

January 1, 2006
Author(s)
D J. Fry, B Langhorst, Haonan Wang, Barry J. Bauer, Erik K. Hobbie
We have used a polarization modulation technique to investigate optical anisotropy of multi-walled and single-walled carbon nanotubes suspended in a variety of solvents. Measurement of birefringence and dichroism have been performed as a function of shear
