Process development of starch hydrolysis using mixing characteristics of Taylor vortices

A concept of membrane CTF (Couette-Taylor flow) reactor applicable to gas-liquid processes has been presented. Its fundamental hydrodynamic and kinetic properties have been discussed. In the experiments high values of the mass transfer coefficients, k L a, of the order of 0.1 s -1 have been obtained and a relatively weak influence of the liquid viscosity on the values of the mass transfer coefficients has been observed. To eliminate moving elements of the reactor, a replacement of the rotor by a static helical ribbon guide which forces the helicoidal flow of the fluid has been proposed for the same operating conditions.

Classification of flow regimes in gas-liquid horizontal Couette-Taylor flow using dimensionless criteria

AbstractThe definition of Reynolds number (Re) in a Taylor-Couette flow for a shear-thinning fluid is discussed in this paper. Since the shear-thinning property causes spatial distribution of fluid viscosity in a Taylor-Couette flow reactor (TCFR), a method to determine Re by using a numerical simulation is suggested. The effective viscosity (ηeff) in Re was the average viscosity using a weight of dissipation functionηeff=∑i=1Nγ⋅i2ηiΔVi/∑i=1Nγ⋅i2ΔVi,
