Webbregime and stability in vertical up flow condensing. A correlation is presented for predicting the transition from a stable annular film flow to a slugging regime. Techniques for estimating pressure drop and inventory are provided. Condensing heat transfer coefficients for potassium and rubidium are measured WebbBoe and Jansen et al. presented, respectively, flow regime maps for predicting the severe slug flow regimes, where the boundaries were determined analytically. Huawei [ 7 ] studied the characteristics of severe slugging in pipeline-riser system and catenary riser system by detailed laboratory experiment and developed a mathematical model for severe slugging. reading minds through body language summary

WebbAs well as the vertical slug flow work, the thesis also presents results obtained in testing the models capabilities to simulate two other effects found in two-phase flows in pipes. The first is the hysteresis phenomena found in horizontal pipes, where the point of transition from stratified flow to slug flow and vice versa is found to shift depending on … Webbflow regime mapping experiments performed in various sized 3D printed fluidized beds (hydraulic diameters of 3–15 mm) containing four different particles exhibiting Geldart A and B behavior. Using high speed camera videos and pressure drop data, we identify preliminary flow regime boundaries on a plot of dimensionless WebbIn Oil and gas productions, the severe slug is an undesired flow regime due to the negative impact on the production rate and facility safety. This study examines the severe riser-induced slugs’ influence on a typical separation process, consisting of a 3-phase gravity separator physically linked to a deoiling hydrocyclone.
