Monodisperse Systems of Spherical Drops or Bubbles

For the Stokes motion of spherical drops and bubbles, the cell Happel model (see Section 2.9) results in the following expression for the mean Sherwood number [503]  

For high Reynolds numbers Re = aU jv 500, the Sherwood number in the constrained flow of gas bubbles can be evaluated by the formula [263] 

We note that in [421], the cell flow model was used for the investigation of mass and heat transfer in monodisperse systems of spherical drops, bubbles, or solid particles for Re 250 and 0 f 0.5.
