Shaken, and stirred: Scaling up bioreactors` fluid dynamics
(PHYSorg.com Physics)

Bioreactors are widely used to produce different therapeutics in the biopharmaceutical and regenerative medicine industries. Drug development relies on small multi-well plates shaken around an orbital diameter, while production-scale bioreactors are agitated by stirring. These different methods yield different fluid dynamics, making it difficult to scale lab findings to industry.
