Slug flow force calculation
WebbThe default cut-off frequency in Caesar II is 33 Hz, which is too low for predicting the dynamic response for slug flows. The rise time of slug loads is in the order of 10ms, resulting in a minimum input frequency of 50 Hz. Increasing the cut-off frequency increases the accuracy and reduces the maximum calculated response forces in many cases. Webb1 aug. 2024 · A slug flow with a high and low GVF interval was set as inlet condition, and unsteady numerical simulations and the deformation of the main pump fluid-structure interaction calculation were applied to investigate the internal flow characteristics of the multiphase pump. ...

WebbUtilising the theory of shearing flow over a wavy boundary developed by Benjami (1968), he developed an expression for the drift velocity as a function of pipe diameter. Th incorporation of the drift velocity improved slug length predictions by twenty percent. The rang of slug lengths in this study were twenty-five to one hundred pipe diameters. Webb6 apr. 2024 · Subsea jumpers connecting the underwater wellhead and nearby manifold commonly undergo flow-induced vibration (FIV) due to the spatially frequent alteration in the flow direction, velocity, pressure and phase volume fraction of the oil–gas two-phase flow, potentially leading to fatigue damage.
