Abstract
The present work seeks to explore, experimentally e numerically, the effect of flow in the efficiency of the fluid displacement using Newtonian fluids in a narrow annular. In order to evaluate the efficiency experimentally an experimental rig was built. The test section is composed of 2 stainless steel pipes with 5.7 m length. The inner pipe has an external diameter of 0.089 m while the external pipe has an internal diameter of 0.102 m. The acquisition system allows the evaluation of fluid displacement in real time. The experimental rig was able to capture the fluid displacement by analysis of the pressure and density signals over time. As a whole, these signals allow to evaluate the efficiency of the process of removing the displaced fluid. Results show a decrease in efficiency with the increase in flow rate. The same tendency is observed in the numerical results, where it was observed that when the flow rate is increased the displacing fluid tends to penetrate into the displaced fluid.
