Impact of Dean Vortices on the Integrity Testing of a Continuous Viral Inactivation Reactor [PDF]
Biotechnology Journal, 2018 We propose a standard protocol for integrity testing the residence‐time distribution (RTD) in a “Jig in a Box” design (JIB)—a previously described tortuous‐path, tubular, low‐pH, continuous viral inactivation reactor, ensuring that biopharmaceutical products will be incubated for the required minimum residence time, tmin .

Visualization of Flows in Curved Channels with a Moderate or High Rotation Speed
International Journal of Rotating Machinery, 1997 Flows in channels with streamwise curvature and spanwise rotation are visualized in terms of end-view near the exit of the test sections through injecting smoke into the flows. Two test sections are used, i.e.

Microbial stabilization of grape musts and wines using coiled UV-C reactor
OENO One, 2020 UV-C light is well known for its germicidal properties and is widely used for water disinfection. However, its low penetration into absorbing liquids, such as wines and musts, reduces drastically the microbial inactivation effectiveness.
