Abstract
Transient behaviour of Taylor vortex flow between rotating concentric cylinders after sudden start has been observed by measuring axial velocity distributions V z (z) for Reynolds number between 70–1,300. We found that a somewhat noisy roll structure is established at an early time after the start. Azimuthal partial rolls can exist and fusions of rolls occur. These phenomena dissipate, and while definite sizes and locations of the rolls are adjusted, the system approaches the ordered structure steady state. The time needed for this transient process is in the order of (or shorter than) the diffusion time.
