Reduction of Aerodynamic Drag: Torsion Disc Viscometry.

Abstract

This report describes the design, construction and evaluation of a working torsion disc viscometer. Initial tests at gas pressures between 9.1 mbar and 1000 mbar show that the theory of the instrument is adequate and that the viscometer is capable of detecting small changes in gas viscosity. A thorough investigvation of the effect of radioactive irradiation on gas viscosity will be made shortly, following the work of Kestin and sHah. An analysis of their approach is given here, viewed in the light of our preliminary work, and suggests the most likely ways of achieving a change in gas viscosity. (Author)
