Turbulence and Statistical Mechanics.

Abstract

This report summarized research during the period July 1, 1976 to October 1, 1979 directed to understanding turbulence in superfluid helium heat transport. This study showed, for the first time, how to create a reasonably homogeneous turbulent flow in a test section of a heat flow channel. The first systematic study of the power spectrum of turbulent fluctuations was completed. Several theoretical studies of helium II were also published, treating elementary excitations, temperature dependent energy levels, equations of motion and restricted geometries. (Author)
