Abstract
The acceleration effect on the Taylor-vortex and later developed wavy vortices was investigated from flow visualization techniques in circular Couette system (with the inner cylinder rotating and outer cylinder at rest) as a function of Reynolds number Re. Our results show that when the acceleration is higher than a critical value of about 2.2 s-1, there exists a new flow regime in which the flow pattern shows remarkable resemblance to the regular Taylor vortex flow with shorter axial wavelength. One of the most surprising aspects of this flow is that it occurs in the range of Reynolds number in which the wavy vortex flow is supposed to occur.
