CFD-DPM Model of Gas–Solid Two-Phase Flow Erosion of Needle Throttle Valve

Coatings, Journal Year: 2025, Volume and Issue: 15(2), P. 248 - 248

Published: Feb. 19, 2025

During shale gas field production, wellhead throttle valves are prone to erosion caused by solid particles carried in the stream, posing significant safety risks. Existing studies on primarily focus simple structure like elbows and tees, while research gas–solid two-phase flow needle remains limited. This paper establishes a numerical model based CFD-DPM approach, integrating actual production conditions investigate behavior of under varying openings, particle sizes, inlet velocities, mass rates. The results show that valve spool consistently exhibits highest rate among all components, with most severe localized at its front end. At 1/4 opening, colliding exhibit significantly increased frequency energy when re-entering upstream pipeline, raising risk blockages. Furthermore, opening exceeds 2/4, chamber experiences higher rates than downstream pipelines. study provides critical insights for optimizing design maintenance strategies, thereby enhancing service life ensuring safe production.
