Abstract

The results of studies of the influence of rheological properties of diesel fuels on the pumping process for collapsible pipelines in low temperature conditions. It is established that diesel fuel when they are cooled below the solidification point represent a viscoplastic medium with curves of current, which describes a universal equation of Buckley-Herschel. A refined method for hydraulic calculation of collapsible tubing to determine the head losses to reflect changes in the rheological properties of diesel fuels at low temperatures. The simulation of the processes of transfer of winter diesel fuel for collapsible pipelines in low temperature conditions and offers recommendations for their application in low-temperature conditions.
