Modeling the turbulent flow in bioreactors is very complex from a fluid mechanic point of view. There is turbulent kinetic energy dissipation (TKE) from the agitators, but also stress due to bubble formation and bubble burst. These effects cannot be modeled exactly in shaken systems. We have developed a shaken system that does induce turbulent flow in baffled shake flasks, however, the types of shear might be present in different proportions, compared to a bioreactor. We will be working with academic partners to answer these questions.
