✦ Synopsis
In the experimental part of this study, pressure drops that occur in the flow of a low density spherical capsule train conveyed by water in a horizontal pipe were found to be 5-30% of the capsule transport concentrations. The developed experimental relations were compared with wellknown relations used for slurry flow. Experimental variables (i.e. bulk velocity, diameter of particle or capsule, diameter of pipe, concentration of particle, density of particle, etc.) were applied to the pressure gradient expressions developed for the slurry flow (asymmetric suspension flow), so that the pressure gradients calculated for a concentration by 5% and 10% were compared with the experimental findings and with the developed mathematical model. It was observed that the pressure gradient expressions of the slurry flow did not simulate the experimental results of the capsule flow. However, a comparison of the empirical expression developed for the pressure drops of the spherical capsule train flow in region (2.5 × 10 4 b Re b 1.5 × 10 5 ) with the experimental findings revealed an average deviation of 3.37%.
