Abstract

In this study, two-phase air/water horizontal flow characteristics with different conduit geometries were investigated. After mixing in a horizontal feeding conduit (100 cm long and 2.54 cm ID) the two-phase, air/water fluid passes through an industrial nozzle, which generates spray. Three different novel geometries were investigated in this study along with the existing design. Flow stability and different flow regimes (dispersed, intermittent and slug) for these three types of geometries were investigated. It is observed that when the input liquid content (εL) decreased to 0.5 (high ALR), the two-phase flow became unstable. It is concluded that the novel geometries are capable of producing more stable and dispersed two-phase flow pattern and spray in an industrial nozzle due to enhanced turbulent mixing.
