Pressure Drop Characteristics of Bi-Modal Slurry at Medium Concentration in Straight Horizontal Pipes
نویسندگان
چکیده
In the present study, pressure drop have been measured for narrow sized silica sand slurry and bimodal slurry consisting of narrow sized silica sand and fly ash as fine particles in different proportions keeping the overall efflux concentration same using a pilot plant test loop. The pressure drop has been measured over a length of 4.0 m in 50 mm NB diameter pipe line for fully developed flow. Bi-model slurry pressure drop measurements at efflux concentration of 20.4% (by weight) shows that the pressure drop reduces considerably with addition of the fine particles. This reduction is in pressure drop is more at lower velocities. For bi-model slurry the deposition velocity reduces slightly with increase in percentage of fines.
