... Abstract. A new predictive model for hydrate formation kinetics that captures the porous structure evolution in time is coupled with a multiphase flow mechanistic model. It is assumed that the hydrate particles behave as sponges, related to hydrate formation under flow shear. The multiphase...

For simulations of hydrate-forming oil-dominated flows in an experimental flow loop, the hydrate cut, subcooling, slurry viscosity and water...

... 1 INTRODUCTION Particle transportation is a common flow assurance problem occurring in oil and gas pipelines. When production takes place in oil and gas wells, oil, gas, water and impurities are produced and transported through the pipeline. Common impurities produced in oil and gas wells...

... ABSTRACT The present work shows the methodology followed in order to implement and validate a sand transport model within a commercial multiphase simulator. Several published correlations for critical velocity, i.e. the velocity required to maintain suspended the sand particles, were...

ECT is a first of its kind erosion control technology to reduce metal loss due to sand erosion by redistributing sand particles in a flow field. CFD was used for designing the test rig and the technology itself. This paper will highlight the process...

The approach assumes that the flow consists of a sand bed and two mixture layers: liquid-continuous with dispersed particles and gas-continuous with dispersed droplets. The proposed model comprises one momentum equation for each...
