Effect of dilute polymer solutions on discharge coefficients of fluid meters

Conference · · Mech. Eng.; (United States)
OSTI ID:5323747
Experimental studies concerning the effect of dilute polymer solutions on the discharge coefficients of several fluid meters are described. The polymers were PEO (polyox coagulant), guar gum (Jaguar 508), and polyacrylamide (polyhall 295). The experimental data showed that the discharge coefficients of the fluid meters are generally changed with polymer addition. In order to explain the effect of polymer additives, the submerged laminar jets of very dilute solutions also were studied. Based on the studies and the published results, the increase in the discharge coefficient of the fluid meter is shown to be caused by a modified boundary layer and normal stress differences developed in the process of deformation.
