ACAV A2

Hydrodynamic factors
When shear rate is high enough structures break down, and viscosity depends mostly on hydrodynamic factors.

Energy is lost because particles disturb flowing of water phase and collide with each other.

The most important hydrodynamic factors are:
- Solids content (i.e. volume fraction of particles)
- Particles size
- Particle size distribution
- Viscosity of continuos (water) phase
- Shape of the particles

Extensional Viscosity
Extensional viscosity together with hydrodynamics is another important factor that has a significant importance to the viscosity of the high shears.

ACAV A2 is able to measure shear rates from 100 up to 10 000 000 1/s covering all important shear rates from the pumping and the piping to the most modern coaters.
