Slit-shaped nozzle

StarLam microstructured mixers consist of disk-like platelets with a hollow starshaped feeding zone where the fluid is re-directed into an inner central circular mixing zone (Fig. 6.6) [21] (see also Refs. [1, 9]). Many such platelets form a complete, rod-shaped inner mixing channel into which the several streams are injected, virtually via small slit-like nozzles. For efficient mixing, injection in the turbulent range is advised. The flow properties at small Re are less well known.
