Abstract
In the process of oil extraction and production, several patterns of liquid-gas two-phase flow can occur. The efficiency of this process can be greatly increased with the use of equipment capable of performing phase separation, if possible still on the seabed. Such devices, known separators have high separation efficiency but usually, its elevated size can be prejudicial. Therefore, a device has been developed capable of dividing the flow into more separators, making possible them to be smaller and consequently facilitating installation, maintenance, and construction. The distribution system here studied has a cyclonic chamber, in which an upward liquid film flow is formed under the influence of the centrifugal and gravitational fields. The development of the liquid film flow is numerically analyzed using ANSYS-CFX and an experimental bench was built in order to validate the numerical model. Next, the model was used to determine the variables that control the flow inside the cyclonic chamber. The experimental data were obtained using an ultrasound technique and a comparison with the numerical model yielded a maximum difference of 38.5% in the value of the average liquid film thickness inside the cyclonic chamber.
