EXPERIMENTAL INVESTIGATION ON PRESSURE DROPS IN FIXED POROUS BEDS PACKED WITH SAND PARTICLES

RÉSUMÉ
This paper reports an experimental study on the pressure drop characteristics infixed beds packed with sand particles. Both single and two-phase flow tests are performed on the test facility, which is designed and constructed to investigate the friction laws of adiabatic single- and two-phase flow through a porous bed. From the single-phase flow test, the effective diameter of bed packed with sand particles is derived from the measured pressure drops and the Ergun equation. Based on this effective diameter, two-phase flow tests are performed and the prediction models are verified by comparing the measured data and the calculations with different analysis models. The results show that the measured pressure drops increase gradually with fluid flowrate for two-phase flow in the bed of smaller sand particles, and the predictions of the Reed model are closer to the measured data. For the bed with coarse sand particles, the pressure drops show a down-up tendency, and only the models considering the interface drag could predict the down-up tendency. But the prediction results are significant deviations from the experimental data.
