LAMINAR/TURBULENT TRANSITION OF DENSE NON-NEWTONIAN SLURRIES

Vlasak P., Chara Z.
pages 264 - +13p., full text

Pipeline system should be operated out of transitional regime because of the flow instability at this area, sudden flow pattern change and origination of concentration waves. The optimum operational condition is slightly above the laminar/turbulent transition zone, where flow conditions should be often very attractive from an economic point of view. Results of experimental investigation of water mixtures of kaolin and fluidic ash in horizontal straight pipes are presented. It was found that laminar/turbulent transition zone can be characterised by unstable flow condition indicated by the pressure fluctuations.
