1. A method for shearing a particle within a fluid, comprising:
rotating a disk of a turbine at a selected speed;
flowing the fluid across a surface of the disk to create a shear stress within the fluid due to a difference between a first fluid velocity at a boundary layer of the disk and a second fluid velocity at a distance from the disk;
imparting the shear stress to the additive particle within the fluid to disintegrate the additive particle; and
expelling the fluid from the turbine at a fluid outlet of the turbine.
