Main areas
Rheological studies of organic fluids and suspensions
Develop of rheometers to coarse settling agricultural suspensions ( rotational viscometer and tube type viscometer

Pumping tests of rotary lobe pumps






Results
Connection of rheological properties with concrete handling processes
  • Pipeline transport (laminar, turbulent, software)
  • Improvement and testing of rotary lobe pumps (pulsation, wear, gap flow, pressure and suction behaviour)
  • Use of centrifugal pumps on liquid feeding (pressure and suction behaviour)
  • Mixing and homogenization
  • Effect of feed enzymes on flow behaviour of liquid feed
  • Rheological properties of biological fluids and suspensions
  • Effects of coferments on the flow behaviour of liquid manure and bio-slurries
