Turbulent flow: “non-linear” flow lines. Impossible to predict the exact movement of the fluid. Very quick.
For rotational systems, this means that the fluid’s movement must be circumferential. When the internal
forces of a fluid end up being too great, the fluid can become a turbulent flow, in that the particles that
make it up become unpredictable, making it impossible to analyse it with standard mathematical models.
This turbulence creates a false reading which is a lot higher than the real one, without linear growth and
totally unpredictable.
For the following geometries, these transition points have been found to be approximate to turbulent flow:
1)
Spindle L1: 15 cP to 60 rpm
2)
Spindle R1: 100 cP to 50 rpm
3)
Adaptor LCP: 0.85 cP to 60 rpm
Turbulent flow conditions will always exist in these conditions as long as the RPM/cP ratio exceeds the
values listed above.
