Abstract
The characteristics of heat transfer affected by Taylor vortex motion were investigated experimentally by the use of electrochemical method and theoretically with the aid of the nonlinear theory suggested by J. T. Stuart. The present non-linear theory, which considers the effect of the fundamentals of disturbances on heat transfer, especially in the wide gap problem, is also applicable to the heat-transfer problem in the range of 1<Re/Recr<2 for fluid with Pr=1. The local Nusselt numbers (Sherwood numbers) measured by means of electrochemical technique show a remarkable sinusoidal periodicity in the axial direction due to Taylor vortex motion, except for their cycloidal periodicity in a very short supercritical range of Reynolds number.
The values of skin friction and heat-transfer coefficient calculated by the semiempirical modification of the equilibrium amplitude of supercritical disturbances agree quite well with measurements over an unexpectedly wide range of Reynolds number (2<Re/Recr<20) where higher-order disturbances should be taken into account.
