The “Sheeter” daemon's main purpose is to detect holes in particle fluids and fill them, but without increasing the emitter’s “Resolution” value. The result is a smooth stream of particles, perfectly suited for high-velocity and slow-motion simulations, or fluid-object collisions.
Linked Fluids
All fluid containers inside the drag-and-drop field will be affected by the daemon. The first fluid container in the scene is linked automatically, others have to be attached manually.

Particle A is moving at a certain velocity which also determines its direction – this is the motion vector. Another vector points in the direction of particle B. The angle (α) between both vectors is compared against “Alignment Threshold”. If this angle is smaller than the given parameter value then a new particle will be created between A and B. The following illustration explains this concept:→ take image from http://support.nextlimit.com/display/rf2015docs/Daemons+-+Sheeter
Use Relative Speed
By taking the particles' speed into account you are able to do a lot of interesting things:
