Effects of Scale and Continuous Phase Viscosity

The effects of the magnitude of tjc have already been discussed. In regime TI it would have no effect on droplet size, in regime TV a larger value would lead to smaller drops, and this effect would be even stronger in regime LV The equations 

If rjc is increased by adding high polymers, this may readily lead to turbulence depression. This is of special importance in the regime TI. It has been studied by Walstra, who showed that addition of polymers caused d to increase and ci (the spread in droplet size) to decrease. This would agree with the smallest eddies being removed from the eddy spectrum.
