Caracterização experimental da separação gás-líquido em uma junção do tipo T inclinada
The two-phase flows at a T-Junction is a common feature in many industrial processes, such as oil field flow lines, pipeline networks and refinery streams to divide or combine flows. When a gas-liquid mixture flows through a junction, the phases can be separated unevenly such that the qualities in …
