- Abstract
Horizontal hydraulic transport of ice particulates suspended in water is a well-known practice used for cooling systems in industry. Many advantages of hydraulic transport include its environmentally friendly application and a relatively low cost of maintenance and operation. This study presents a one-dimensional mathematical model, developed for simulating a pressure drop of solid and water two-phase fluid flow inside a horizontal pipe. The impact of different parameters such as suspension-wall friction coefficients, suspension-viscosity models and solid volumetric concentrations on the pressure drop of the capsule flow were evaluated. The results of the simulations were validated by the results of two different experiments. The first experiment was performed with anomalous-shaped capsules, which had a higher density than the density of the liquid flow while the second experiment was performed with capsules having a spherical shape and a density lower than the density of the carrier liquid flow in the pipe. The measurements were carried out in the horizontal pipe. In both experiments, the carrier fluid was water. The results of this modeling study revealed that the proposed model can be effectively used to predict the pressure drop of ice and water two-phase flow with sufficient precision.
