Abstract

The Taylor-Couette system keeps making subject to countless studies. It is used in catalytic reactors, electrochemistry, photochemistry, biochemistry and polymerization, as well as in mass transfer operations (extraction, tangential filtration, crystallization and dialysis). This work deals with a numerical study dedicated to a Taylor-Couette flow considering the influence of a pulsatile dynamic superimposed to the rotative inner cylinder. Simulations are implemented on the FLUENT commercial package where a three-dimensional and incompressible flow is considered. It is shown that the suggested controlling technique fundamentally alters the physical flow behavior resulting in substantial turbulence enhancement to which transition is instilled at a Taylor number of Ta = 17 instead of Ta = 41.33 corresponding to the non-controlled case.
