ANALYSIS OF VOID FRACTION PHASE DISTRIBUTION OF GAS-LIQUID FLOW IN A HORIZONTAL PIPE USING WIRE MESH SENSOR DATA

Abstract:
Gas-liquid flows are commonly encountered in various industrial processes, including oil and gas transportation, chemical engineering, and nuclear power plants. Accurate measurement and analysis of the void fraction phase distribution, which represents the distribution of gas and liquid phases within a flowing mixture, is crucial for understanding and optimizing the performance of these systems. In this study, we focus on analyzing the void fraction phase distribution of gas-liquid flow in a horizontal pipe using wire mesh sensor data.

Wire mesh sensors have gained significant attention in recent years due to their ability to provide high-resolution spatial and temporal data of multiphase flows. These sensors consist of an array of conductive wires, which are used to measure the local conductivity of the flowing mixture. By analyzing the electrical conductivity data obtained from the wire mesh sensor, it is possible to estimate the void fraction phase distribution along the pipe length.

The objective of this research is to develop a comprehensive methodology for analyzing the wire mesh sensor data and extracting meaningful information about the void fraction phase distribution. The proposed methodology involves preprocessing the raw sensor data, calibrating the sensor response, and applying appropriate algorithms for void fraction estimation. Various signal processing techniques, such as filtering, noise reduction, and feature extraction, are employed to enhance the accuracy and reliability of the analysis.

Experimental investigations are conducted using a test rig consisting of a horizontal pipe setup with a wire mesh sensor installed at a specific location. Different gas and liquid flow rates are employed to simulate a wide range of operating conditions. The wire mesh sensor data, along with reference measurements obtained from conventional techniques, are used for validation and verification purposes.

The analysis of the wire mesh sensor data provides valuable insights into the void fraction phase distribution, including the identification of flow patterns, the determination of slug and annular flow regimes, and the quantification of the gas and liquid holdup. The results obtained from this study contribute to a better understanding of gas-liquid flow behavior in horizontal pipes and can be utilized for process optimization and design improvement.
