MODES OF INSTABILITY IN SPIRAL FLOW BETWEEN ROTATING CYLINDERS,

Abstract

This paper gives the results of an experimental investigation of the stability of spiral flow between rotating cylinders with respect to axisymmetric and nonaxisymmetric disturbances. Various modes of instability were detected by observing visually characteristic ink patterns in the fluid. The effect of small axial flow upon all of the modes was to give an approximately parabolic dependence of the critical Taylor number on the axial flow rate. In the case of an axisymmetric mode, agreement with the theory of Krueger and Di Prima (1964) was found to be excellent.
