IbD PU Deliverable 3.1 The behaviour of a Newtonian fluid confined in the annulus (with a stationary outer cylinder) can be characterized by the rotational Reynolds number, 𝑅𝑒 = 𝜔𝑟𝑖(𝑟𝑜 − 𝑟𝑖) 𝜈 where 𝜔 is the inner cylinder angular velocity, 𝑟𝑖 and 𝑟𝑜 are the radii of the inner and outer cylinders, respectively, and 𝜈 is the kinematic viscosity of the fluid. When the Reynolds number is increased above but very close to a critical point which is dependent on the device physical parameters, it is found that the laminar vortex flow (LVF) is unstable with respect to axisymmetric perturbations with wave numbers in the range bounded by the neutral stability curve and Taylor vortices appear in the flow field which is called Taylor vortex flow (TVF). The critical Reynolds number is dependent on the reactor and fluid parameters and can fall in the range of 50-200. On further increasing Re above the critical value, the system undergoes a series of different flow regimes spanning laminar to turbulent regimes, which include wavy vortex flow (WVF), modulated wavy vortex flow, (MWVF), and turbulent Taylor vortex flow (TTVF), as depicted in Figure 22 below. Figure 22. Example flow regimes of Taylor-Couette flow (a) TVF (b) WVF (c) MWVF (d) TTVF (Fenstermacher et al., 1979). The Taylor-Couette reactor (TCR), based on the flow property which leads to a residence time distribution similar to the plug-flow reactor with a good mixing in each vortex, has the advantages of efficient heat transfer and low hydrodynamic shear rates in the liquid phase. The flow regimes of TCR can be controlled by the rotating velocity of the inner cylinder. 25PDF Image | Solids handling for intensified process technology
