Abstract
Multiphase flow occurs often in nature as in industry applications, and its knowledge is of particular importance. One of the most common types of multiphase flow is the two-phase gas-liquid flow. The behavior of the gas-liquid flow depends on liquid and gas flow rates at the inlet of the pipe, and fluid and geometric properties. Two-phase flow is frequently found within the oil and natural gas industry. Two-phase flow in pipeline can be present different geometric distributions named flow patterns that depend mainly on oil and gas superficial velocities and pressure as the interfacial phenomena between the phases. In this work has been developed an experimental study about air-water two-phase flow in a horizontal pipeline to measure the pressure drop for various volumetric flow conditions on pipe entrance, both to gas as liquids. The flow range analyzed in this work, between 5 and 30 liters per minute for the liquid and between 5 and 40 liters per mine of gas flow rate, corresponding to slug flow pattern which is characterized by the intermittent passage of elongated bubbles of gas followed by a liquid slug, which is one of the most common patterns for oil extraction. To accomplish this goal, an experimental facility at GPEM-UniBrasil lab consisting of a 25.8 mm ID, 11-m long, transparent pipeline was used the analysis performed in this paper seeks a best understanding of the flow behavior, which is of great importance in the industry.
