Ribbon impellers are most prevalently used
for batch mixing applications within the chemical and petrochemical industries
by use of helical ribbon and helical ribbon screw impellers. The study
of the deformation and flow of complex fluids (rheology) is where Mixing
Solutions are expert, and where we can add the greatest value to your
process.
Our expertise in helping companies achieve
the highest blend rates possible for the mixing of pseudoplastic fluids
of high viscosity is unsurpassed in the industry.
| The design of such impellers is based on an assumed linear relation
between fluid shear rate and the rotational speed of the impeller.
A number of computational fluid dynamics (CFD) simulations of the
flow field are usually carried out to confirm these characteristics.
After all, we know better than anyone that the shear rate varies greatly
from one mixing vessel to another. However, the linear relationship
between the impeller speed and the local fluid shear rate near the
tip of the impeller, which we can demonstrate in our laboratory environment,
enables us to customise our solution based on your individual geometric
parameters. |
