## Abstract It is well known that helical ribbon (HR) impellers exhibit poor bottom pumping properties. Three different HR impeller geometries, varying in their bottom design, are compared in terms of their mixing performance. Particular emphasis is given to the improvement of pumping capabilities.
## Abstract An 11‐L helical ribbon impeller (HRI) bioreactor was tested for the culture of __Spodoptera frugiperda__ (Sf−9) cells. This impeller and surface baffling ensured homogeneous mixing and high oxygen transfer through surface aeration and surface‐induced babble generation. Serum‐supplemente
## Abstract A commercial CFD package was used to simulate the 3D flow field generated in a cylindrical tank by a helical ribbon impeller. The study was carried out using a pseudoplastic fluid with yield stress in the laminar mixing region. Ultrasonic Doppler velocimetry (UDV), a noninvasive fluid f
