Characterizations of gas-liquid interface distribution and slug evolution in a vertical pipe

Petroleum Science, Journal Year: 2023, Volume and Issue: 20(5), P. 3157 - 3171

Large vertical pipes are key structures connecting subsea wells to offshore platforms. However, existing studies mainly focus on small pipes. In a acrylic pipe with 80 mm inner diameter and 11 m height, high-speed camera was used visually research the influences of diameters, liquid properties inlet effect air-water co-flow characteristic. Different flow regime maps (diameters in range 50–189 mm) were compared critical gas velocity transition boundary from bubble slug tended increase diameters at D ≥ mm. Drift-flux models established different regimes have significant drift coefficients (void fraction α ≤ 0.4). The influence turbulent gas-liquid interface distribution gradually weakened disappeared base 85D, where fully developed. Slug frequency has trend first then decrease Weber numbers increasing low superficial velocities (JL 0.31 m/s). And basis this law, new correlation proposed. It found that there an exponential relationship between ratio lengths Taylor void fraction.

Machine Learning Model for Leak Detection Using Water Pipeline Vibration Sensor

Sensors, Journal Year: 2023, Volume and Issue: 23(21), P. 8935 - 8935

Published: Nov. 2, 2023

Water leakage from aging water and wastewater pipes is a persistent problem, necessitating the improvement of existing leak detection response methods. In this study, we conducted an analysis essential features based on data collected sensors installed at meter boxes outlets pipelines. The pipeline through vibration sensor were preprocessed by converting it into tabular form frequency band applied to various machine learning models. characteristics each model analyzed, XGBoost was selected as most suitable with high accuracy 99.79%. These systems can effectively reduce time, minimize waste, economic losses. Additionally, technology be fields that utilize pipes, making widely applicable.
