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
