Visualisation of chemistry in flow
… bands was explained by the flow, in which Taylor vortices translate axially up the tube in an approximation of plug flow. The rotation rate of the inner cylinder was identified as a new parameter for control of both the stability and wavelength of FDO patterns. Optical imaging was able to …

CFD Study of Taylor-Like Vortices in Swirling Flows
… chamber using CFD, a similarity with the Taylor vortices instability has been observed. Similar to the classic Taylor-Couette flow system, a secondary flow field in the form of wavy toroidal vortices spaced regularly along the axial direction appear under certain critical conditions. The …

Nonlinear and non-modal stability of structures evolving in shear flows
… important secondary nonlinear structure called a Taylor vortex to be determined. From this the distinct tertiary states which emerge as Taylor vortices break down are characterized and their bifurcation behaviour is studied. Also, non-modal stability analyses are conducted in rotating plane …

Experimental Investigation on Heat Transfer and Pressure Loss Characteristics of Rotating Rectangular and Annular Ducts
… ratios. Along the centerline, the onset of Taylor vortices can be seen enhancing the Nusselt number in regions where the flow should be fully developed. This effect can also be seen enhancing the heat transfer in the fully developed region. The presence of Taylor vortices also adds …

An experimental investigation of diffuse optical scattering from stationary and flowing dispersions
… Reynolds number are explicable in terms of Taylor vortices. The shear-induced changes in S in laminar flow are shown to be a useful practical measure of the state of flocculation of the dispersion.

Stuck pipe prediction in deviated wellbores: a numerical and statistical analysis.
… and do not adequately account for the effect of vortices created as the drill string rotates about its axis. This thesis addresses both shortcomings, and presents improved cutting transport models that consider hindered centrifugal settling of drilled cuttings, effect of Taylor vortices and Van …

Helical magnetorotational instability in MHD Taylor-Couette flow
… and today such setup is usually referred as a Taylor-Couette flow. To prove experimentally the existence of MRI in a magnetized Taylor-Couette flow is a demanding task and different MHD groups around the world try to achieve it. The main problem lies in the fact that laboratory liquid metals …
