In order to enlarge the pipeline lengths in the field, tests were carried out in a laboratory test-loop in order to try to understand the anomalous (intermittent) flow behaviour and to solve the problem. Based on data obtained from these laboratory tests and using a generalized REYNOLDS number it was possible to obtain results that fit the MOODY ROUSE diagram.801-803engDischarge (fluid mechanics)Laminar flowMathematical modelsOre tailingsPipelinesPulsatile flowReynolds numberShear stressTurbulent flowHerschel Buckley modelMoody Rouse diagramPumping systemsRheologyArtigoAcesso restrito2-s2.0-00285266293756802878031727
