Study of the hydrodynamic behaviour of an air-lift fermenter in a transverse magnetic field

Abstract EN

Hydrodynamics of a three-phase* air-lift fermenter of magnetic particles has;Men investigated: in the presence of external transverse magnetic field.

Experiments: were performed by first applying, the magnetic field to a static bed.

Parallel to the increasing gas flow, several bed regimes have been observed including, initial packed* stabilized, and fiuidized bed.

Bed expansion before the.

onset of: flliidization increases; with the increase of magnetic field intensity.

Minimum, fluidization velocity was found Eq be strongly dependent on magnetic Held intensity.

Magnetic.

field intensity alsq: affects; liquid;,circulation velocity.

A photo cell was used to measure the water flow rate in (he down coiner of the reactor.
