WitrynaThe impeller must provide sufficiently rapid agitation to disperse all compounds and achieve an effectively homogeneous concentration inside the bioreactor. The technical design of an STBR for a bioprocess must determine the required volume, which depends on the production. WitrynaFor flat and canted impeller applications, TOR should range between 40 and 85 s. As the TOR approaches 40 s, the chance for vortex formation and possible air entrainment increases. At values greater than 85 s, proper suspension may be jeopardized and solids will begin to settle.

Witryna16 wrz 2024 · The impeller is the first component to investigate when assessing centrifugal pump efficiency. For any impeller, we know that its head varies as a square of the change in speed. By doubling the speed, the head will increase four times as much. The same applies to small changes in diameter if you keep the speed constant. WitrynaThat is, a tip vortex is generated at the impeller counterturn and disappears till the next impeller counterturn, keeping the center at the impeller tip at Re=2.3, while the tip …
