Abstract

This study investigates the pressure drop in horizontal pipes packed with large particles and small pipe-to-particle diameter ratio both experimentally and numerically. Two horizontal pipes of 0.1905 and 0.0254m inner diameter filled with cylindrical or spherical particles are used to collect the experimental data for single and two-phase flow. The drift-flux model used for multiphase flow earlier is modified to predict the pressure drop in porous media. The porosity has same value for both pipes when they packed with cylindrical particles which is 0.75, but has different values when packed with spherical particles, 0.7 for the large pipe and 0.57 for the small pipe. Empirical models from literature are used to calculate the pressure drop of single phase and two-phase flow. The experimental results are in good agreement with the empirical model for single phase flows. However, the two-phase flow results are very much scattered around the trend line indicating the need for more work to improve the empirical models. The results from drift-flux model are in good agreement with experimental data.
