This paper investigates the flow structure and pattern transition within a conical ribbed Taylor–Couette reactor (TCR), which is 4 mm in gap width 200 height, via particle image velocimetry (PIV) numerical simulation methods. The effect of various parameters on vortex transition, including structural ribs (rib spacing rib width) operating (Taylor number axial Reynolds number), were investigated...

The quantitative analysis of low-dimensional chaotic dynamical systems has been an active area of research for many years. Up until now, most work has concentrated on the analysis of time series data from laboratory experiments and numerical simulations. Examples include Rayleigh-Bénard convection, Couette-Taylor fluid flow, and the Belousov-Zhabotinskii chemical reaction [Libchaber, Fauve & La...

We report the results of a theoretical study of the stability of a Couette flow of dilute and concentrated suspensions of stiff fibers. The Ericksen anisotropic fluid rheological equation of state in the wide-gap situation is used to compute the critical Taylor number and wavenumber of the suspension as a function of the aspect ratio of the fibers and the gap-width
