Technical Paper: Validation of a Physically-Based Model for Slug Initiation and Evolution in Hydrodynamic Slug Flow

Society: Other
Paper Number: BHR-2015-A1
Presentation Date: 2015


A mechanistic model has been developed for the rate of initiation of hydrodynamic slugs and has been coupled with improvements in the closure models for slug flow. The resulting Slug Tracking simulator is capable of predicting the slug frequency and slug length distribution, and their evolution along a long pipeline. The simulations are validated against published laboratory data, against data from the large scale Tiller loop, and against field data. For field cases, computed slug lengths and frequencies are typically within a factor of two of measured values; the frequencies compare favorably with the best available correlations.
