... 10-3 lbf/ft (0.072 N/m), respectively. 3.4 Conductivity Probes Output voltages from conductivity probes installed along the test section (Figure 1) were used to calculate parameters such as translational velocity (vt), slug frequency (fs), and dimensionless slug length (Ls/D). Conductivity probes...

... Abstract Over ten different slug frequency models/correlations were evaluated against experimental data as a part of this study. The effect of parameters such as pressure and flow development length on slug frequencies were studied and comparisons with model predictions were made...

... in slug flow. The interference between the slug frequencies of the two pipelines is shown to be largely destructive in nature and acts to reduce outlet flow rate fluctuations. This configuration is shown to also provide advantages in the long-term operation of the pipeline system when pigging, corrosion...

..., respectively. An appropriate instrumentation set, data acquisition system, experimental procedure and data analysis were applied in order to reduce the uncertainty in the acquired data. slug frequency production control production monitoring mixture velocity slug flow viscosity oil viscosity...

... the slug front in laminar slug flow using e.g. Particle Image Velocimetry (PIV). In the present work we use the model of Cook and Behnia as a starting point, even though their model was developed with focus on turbulent flow. 5.2 Slug frequency In a standard unit cell model assuming a constant holdup...

... surface, combined with the Very-Large Eddy Simulation (VLES) approach to cope with turbulence. We will first discuss new results of transition from stratified to slug flow, which agree well with the data as to water hold-up and slug frequency. We will then present new results of bubbly and slug flow...

... ABSTRACT: Slug frequency is a critical characteristic of two-phase slug flow for predicting pressure gradient, erosion/corrosion rates, pipeline structural integrity and designing downstream separation and process facilities. Conversely, slug frequency is the least accurately predicted...

... was developed and solved in Fluent. The model predictions of flow regime transition and slug frequency were compared with experimental data and those of OLGA model. The slug movement was described based on the predicted liquid holdup traces at different locations of the system. Slug mitigation methods...
