Abstract

A study was made of the possible similarity between the development of truncated, inviscid turbulence and the Fermi-Pasta-Ulam (FPU) problem. For the case of a constant time scale, which resembles the FPU problem, a significant increase in the time to achieve equipartition was found when the initial energy was decreased. At first a few modes were generated and only rather late in the spectral development other modes appear and equipartition was established.

Abstract

A procedure has been developed to calculate the frictional coefficient of a porous sphere with radially varying permeability. Application to polymer coils, where permeability values can be derived from sedimentation data at finite concentration, shows agreement with experimental frictional coefficients of polymer coils at infinite dilution.
