Abstract: | Experimental investigations have been carried out to evaluate the two-phase pressure drop across half-inch globe and gate valves for gas-non-Newtonian liquid flow. The non-Newtonian liquids used were different concentrations of dilute solutions of the sodium salt of carboxymethyl cellulose (SCMC), which behaved as pseudoplastic liquids. Generalized correlations in terms of the various physical and dynamic variables of the system have been developed for prediction of the two-phase frictional pressure drop for each valve. Statistical analysis of the correlations suggest that they are of acceptable accuracy. |
