NUMERICAL STUDY ON THE 2-PHASE FLOW DISTRIBUTION IN A T-JUNCTION

The main objective of this paper is to investigate the ability of a tw o-dimensional two-fluid computer code to predict the phase separation in a T-junction. A new semi-implicit numerical scheme is developed for solving the two-fluid model equations. Special attention is directed to the modelling of the constitutive equations for the interfacial fri ction term. Detailed distribution of void fraction, pressure and veloc ities are obtained for an air-water mixture in a vertical tee. Good ag reement was obtained between the computer code results and the experim ental data for the phase separation in the T-junction.
