Abstract

A novel and systematic experimental investigation was conducted on droplet deposition and coalescence in curved pipes. Various curved pipe bends, to be utilized as flow conditioning devices upstream of wet gas separators, were tested. Data were collected for about 200 experimental runs, varying v ratio up to 4.5, for two liquid loadings of 700 and 1400 m3∕MMsm3. The results show that the 180∘ pipe bend and the long elbow bend performances are similar, which are the best among the curved pipes tested. The long elbow bend is recommended for field applications for its performance, availability, and ease of installation. A model for the prediction of droplet deposition in a long elbow bend was developed, based on the physical phenomena, consisting of a force balance and a conservation of angular momentum on a droplet. The model enables tracking the droplet movement in the elbow and identifying the depositing droplets. A comparison between the model predictions and experimental data shows a good agreement with average error about 20%.
