Investigation of Rheological Properties of Dilute Solutions of Polymeric Antimist Agents in Hydrocarbon Fuels.

摘要

A dilute solution of polymeric antimist additive is found to offer unusually high resistance to flow through metal filters. This apparent anomaly is not due to filter plugging or polymer adsorption but may be explained in terms of an elongational viscosity that cannot be observed in ordinary viscometric flow. Measurements in different size filters indicate a slightly higher resistance with finer pore sizes; however, end effects were not significant. Preliminary results indicate that this anomalous resistance may be related to antimisting effectiveness. (Author)
