The paper considers issues associated with predicting the volume of a mixture (transmix) generated during the transportation of consecutive batches of fuels belonging to different groups and grades in collapsible pipelines. The authors present a mathematical model of the fuel mixing process occurring in the course of batching, which is based on Taylor's theory of longitudinal dispersion in turbulent flows. Analytical dependences for expressing the viscosity-temperature characteristics of transported fuels are proposed. The volume of fuel transmix produced during batching in collapsible pipelines is estimated.
