“…Hence, as the momentum distribution parameter is not the priority of this work and its modelling might be a source of uncertainties for the 1D Two-Fluid Model and the Regime Capturing Methodology, is considered to be unity, Eq. (3.17), as commonly found in several publications (Issa & Kempf, 2003;Bonizzi et al, 2009;Carneiro et al, 2011;Han & Guo, 2015;Ferrari et al, 2017).…”

“…With this methodology, the same set of correlations can be used for all the flow patterns, which is in great contrast with the other two approaches. Nevertheless, although very promising and satisfactorily validated for air-water flows (Carneiro et al, 2011;Nieckele et al, 2013;Han & Guo, 2015;Ferrari et al, 2017), this methodology has, with few exceptions, not being much explored for performing 1D…”

“…(3.2) can be rewritten in order to obtain the bulk pressure ̅̅̅ present in just one of the terms, as it can be seen in Eq. (3.7) (Issa & Kempf, 2003;Carneiro et al, 2011), where the area-average and the volumetric-fraction-weighted-mean operators were dropped.…”

“…Therefore, a possible base flow configuration is to consider the flow to be stratified (Issa & Kempf, 2003;Bonizzi et al, 2009;Carneiro et al, 2011;Nieckele et al, 2013). Such configuration consists in a heavier phase, the liquid, in the cases of interest here, located at the bottom of the pipe and a lighter phase, the gas, at its upper part, as illustrated in Figure 3.1.…”

“…As performed in several works (Issa & Kempf, 2003;Bonizzi et al, 2009;Carneiro et al, 2011;Han & Guo, 2015;Ferrari et al, 2017), compressibility is only considered to the gas phase, i.e., the liquid is considered as incompressible.…”

Prediction models for multiphase‐flow‐induced corrosion of API X80 steel in CO₂/H₂S environment

In the offshore oil and gas industry, mainly focusing on the use of rigid or flexible pipes of subsea infrastructure applied to risers or flowlines, one of the greatest difficulties is the interpretation of the combined effects of the various correlated phenomena (hydrodynamic effects of intermittent flow, the effects of corrosivity of the environment in addition to variations in pressure, temperature, and dynamic loading). On the basis of this scenario, defining the degree of severity of each of the correlated system variables becomes of fundamental importance for establishing reliable criteria for selecting materials for subsea application. The established flow pattern directly affects the corrosion rate (or the pipe material mass loss), but the balance of other variables including possible changes in the physical and transported fluid chemical properties may increase the damage up to an order of magnitude, which is a piece of information normally not foreseen in design criteria. Therefore, to improve the understanding of the corrosion study influenced by multiphase flow, a testing loop was designed and assembled at the Corrosion and Protection Laboratory of the Institute for Technological Research, in which API X80 steel coupons were positioned in locations with a 0°and 45°inclinations. Tests were conducted by varying the partial pressure of the gaseous phase containing blends of CO 2 and H 2 S with N 2 balance, mixed with the liquid phase containing light oil and heavy oil in water with salinity (NaCl)simulating oil well conditions with 80% water cut. The main objective of this study is to establish models that can predict the corrosion intensity in conditions close to those obtained experimentally. To achieve results, the multiple regression and Box-Cox transformation methods were applied. These models will make possible damage prediction and optimization of matrix parameters for the multiphase-loop test.
