Description Microalgae cultivation can be made sustainable on a
large-scale by lowering the costs associated with
closed photobioreactors (PBRs). It can be achieved
through the appropriate design of closed PBRs to
achieve maximum productivity. The cultivation of
microalgae is very sensitive to temperature, pH,
shear stress, irradiance, and operating conditions of
the PBR. The understanding of design parameters is
a prerequisite for scale-up of gas-sparged vertical
column PBRs. The hydrodynamics of gas-sparged
vertical column PBRs play a very critical role in the
optimum production of microalgae and avoiding
the carbon loss (unabsorbed CO2 out of total supplied).
In this article, the effects of design parameters
on microalgae productivity in various
vertical column PBRs, i.e., flat panel, bubble column,
and airlift (draft tube) column, are critically
reviewed. The microalgae production in PBRs is
essentially a three-phase operation. Hence, the
hydrodynamic aspects of two- and three-phase flow
in the vertical column PBR are emphasized with
respect to its scale-up prospect. The flow regimes
and CFD modeling aspects of gas-sparged PBRs are
also covered in this review.
