Introduction:

The objective of this case study was to conduct a comprehensive 3D Computational Fluid Dynamics (CFD) analysis of a Wedge Plug Valve under Fully Open & Seated Plug Conditions. The focus was on examining the interaction between steam and coke within the valve, fluid profiles, volume fraction, pressure distribution, and path lines of coke and steam.

Challenges:

Understanding the complex interaction between steam and coke, absent volume fraction data for coke in the steam fluid domain and validating the CFD analysis for real-world accuracy were the primary challenges faced in this study.

Solution:

The solution involved leveraging advanced CFD techniques, including Eulerian- multiphase modelling, to accurately simulate steam and coke interaction within the valve. A detailed analysis of fluid profiles, pressure distribution, and path lines of coke and steam was conducted to pinpoint areas for design enhancement. An iterative design process, informed by CFD insights, was implemented to refine the valve design and address identified issues. Additionally, a collaborative approach was adopted, engaging multidisciplinary teams to collaborate on analysis and design improvement efforts.

Benefits

The multiphase CFD analysis of the Wedge Plug Valve proved to be instrumental in optimizing the valve design, improving performance, and enhancing safety and reliability in steam and coke applications.
