Abstract
On the petroleum industry, in the production, there are single and multiphase flows from the reservoir to the separator through horizontal and vertical lines. Devices such as singularities may increase or decrease fluid kinetics’ energy and to control the flow. These singularities are commonly installed for multiple purposes. One type of restrictions are the valves as chokes and orifice plates, some of them are designed to metering, others are for flow control and/or pressure control. The objective of this paper is to show an experimental study of horizontal single and multiphase flow through orifice plates. The single-phase (liquid) and multiphase experiments (liquid/gas) are being performed, using water, oil and air as working fluids. The objective of this paper is to analyze the behavior of the pressure drop and discharge coefficient (Cd) at different orifices diameters using the literature as background, such as applicable norms for single-phase, empirical correlations and homogenous/nonhomogeneous models for multiphase flows. Results obtained on this research will be compared with literature and the fluid behavior for critical flow and subcritical flow.
