Erratum to the paper Exploiting the Bjerknes force in bubble column reactors by Juerg Ellenberger, Jasper M. van Baten and Rajamani Krishna, Chemical Engineering Science 60 (2005) 5962-5970.
The following corrections are hereby made for some of the equations employed in the above paper. The corrected equations are highlighted in yellow.
The oscillating pressure field experienced by a bubble of volume
is given by:
![]()
Therefore the Bjerknes force acting on the bubble due to volume oscillations is given by the time average of:
, that is,
![]()
The variation of the bubble radius with time is described by the Rayleigh-Plesset (RP) equation given by:

The above corrected equations were implemented and the resulting deviation from the results presented in the paper was negligible.
