Criterion for purely elastic Taylor-Couette instability in the flows of shear-banding fluids [PDF]

, 2011
In the past twenty years, shear-banding flows have been probed by various techniques, such as rheometry, velocimetry and flow birefringence. In micellar solutions, many of the data collected exhibit unexplained spatio-temporal fluctuations.

Heat transfer enhancement and torque reduction by traveling wave-like blowing and suction in turbulent Taylor-Couette flow

Journal of Thermal Science and Technology, 2021
Direct numerical simulations of turbulent Taylor-Couette flows are performed to investigate the effect of a traveling wave control on torque and heat transfer. In the Taylor-Couette flow, inner and outer cylinders are rotating and immobile, respectively,

Optimal Taylor-Couette flow: Radius ratio dependence [PDF]

, 2013
Taylor-Couette flow with independently rotating inner (i) and outer (o) cylinders is explored numerically and experimentally to determine the effects of the radius ratio {\eta} on the system response. Numerical simulations reach Reynolds numbers of up to

Optimal Taylor-Couette flow: direct numerical simulations [PDF]

, 2012
We numerically simulate turbulent Taylor-Couette flow for independently rotating inner and outer cylinders, focusing on the analogy with turbulent Rayleigh-B\'enard flow.

Experimental study of enhanced mixing induced by particles in Taylor–Couette flows [PDF]

, 2016
Local mixing dynamics was recently investigated experimentally in Taylor–Couettesingle-phase flow, thanks to simultaneous Particle Image Velocimetry (PIV) and PlanarLaser-Induced Fluorescence (PLIF) techniques.

Velocity profiles in strongly turbulent Taylor-Couette flow [PDF]

, 2013
We derive the velocity profiles in strongly turbulent Taylor-Couette flow for the general case of independently rotating cylinders. The theory is based on the Navier-Stokes equations in the appropriate (cylinder) geometry.

Experimental investigation of liquid-liquid system drop size distribution in Taylor-Couette flow and its application in the CFD simulation

EPJ Web of Conferences, 2017
Liquid-liquid systems are widely used in the several industries such as food, pharmaceutical, cosmetic, chemical and petroleum. Drop size distribution (DSD) plays a key role as it strongly affects the overall mass and heat transfer in the liquid-liquid ...
