PARAMETERS FOR BED SLIP POINT IN TWO-PHASE PIPELINE FLOW WITH SOLIDS

According to earlier work, the limit of deposition is given by the slip point, when the bed begins to slide, and the pressure gradient at slip point depends on the angle subtended by the bed and other factors. Suitable parameters representative of the pressure gradient, discharge, and concentration of solids at the slip point are expressed in terms of this angle. For specific cases, with given pipe size and particle properties, the angle of deposition can be eliminated by plotting gradient parameters vs discharge parameter. This gives a graph similar to those generally used for plotting experimental results for two-phase pipeline flow, on which the locus of the slip point defines regions with and without deposition. The discharge at the slip point rises to a maximum and then decreases with increasing gradient. In combination with efficiency considerations, this indicates that it is desirable to operate pipelines with high solids concentration.
