Introducing a Web-Based Modelling Tool for Multiphase Flow Characterization

Explore Flow Model

Understanding flow characterization is essential for predicting and assessing the corrosivity of systems. Over time, significant progress has been made in studying the relationship between flow dynamics and corrosion. To support these efforts, various flow models have been developed – each tailored to specific conditions.

Multiphase flow – commonly encountered in the petroleum, chemical, and nuclear industries – is significantly more complex due to the challenges of characterizing phase distribution and flow patterns. To address this complexity, a variety of multiphase flow models have been introduced. Some are based on mechanistic approaches, while others rely on empirical correlations derived from laboratory experiments or field data.

However, empirical models often fall short, as they are limited to the conditions under which they were developed. These models typically cannot be applied confidently across the wide range of fluid types and operating conditions found in oil and gas fields. Moreover, many exhibit large discontinuities at flow pattern transitions, causing convergence issues when used in simulations of petroleum reservoirs and production facilities. Some models are also constrained to specific piping configurations, leading to further complications when transitioning between systems.

An ideal flow model should accommodate a full range of piping inclinations and reliably output key flow parameters – flow regime, liquid holdup, pressure drop, and wall shear stress – which are critical for corrosion assessment and risk mitigation.

Introducing the Flow Model

The newly launched web-based mechanistic model integrates a broad set of industry-standard correlations for both single-phase and multiphase flow characterization. It covers the entire range of piping inclinations and calculates essential flow parameters such as flow regime, liquid holdup, pressure drop, and wall shear stress—enabling engineers to assess system corrosivity and implement more effective mitigation strategies.
