|Title:||Numerical Simulation Of Two-phase Flow Distribution In A Vertical Square Bend|
|Author:||Moura Luiz Felipe M.|

|Abstract:||The principal objective of this paper is to investigate numerically the gas-liquid phase distribution in a vertical square bend. A two-dimensional computer code was used to solve the two-fluid model equations, using the finite volume method. Special attention is directed to the modeling of the constitutive equation for the interfacial friction term. The phase distribution was simulated in the middle plane of a vertical bend with a square cross section (2 inches × 2 inches. Nine different inlet boundary conditions were used in order to simulate vertical bubbly flow, slug flow, churn flow and dispersed bubble flow patterns. Detailed distribution of the void friction, pressure and velocity of both phases are presented. The general behaviour of the two-phase flow distribution in the bend is in agreement with the available experimental data. This work includes also the investigation of the gravity influence on the two-phase flow distribution phenomena.|
