Research on the water–gas flow pattern of in horizontal aeration pipes
Aeration irrigation has garnered significant attention due to its effectiveness in enhancing crop yield and water use efficiency. Understanding the two-phase flow mechanism of water–gas in the aeration pipeline is of great significance for promoting the development of the aeration irrigation system. In this study, a formula for calculating Reynolds number of water–gas flow in aeration pipeline was established by combining theoretical analysis with experimental verification. In addition, based on the YOLO v5 image classification model, a classification and detection model of water–gas flow pattern was proposed. The results show that increasing aeration rate can increase pipeline pressure. The overall accuracy of the developed flow pattern detection software was 86.3%, which can meet the requirements of practical application. Finally, based on image classification and theoretical analysis, the formulas of the corresponding flow patterns were obtained. This study provides a solution for determining the two-phase flow pattern of water–gas in aerated irrigation system, which was of great significance for improving the hydraulic calculation of aerated irrigation system and promoting the wide application of aerated irrigation technology.
期刊介绍：
Meccanica focuses on the methodological framework shared by mechanical scientists when addressing theoretical or applied problems. Original papers address various aspects of mechanical and mathematical modeling, of solution, as well as of analysis of system behavior. The journal explores fundamental and applications issues in established areas of mechanics research as well as in emerging fields; contemporary research on general mechanics, solid and structural mechanics, fluid mechanics, and mechanics of machines; interdisciplinary fields between mechanics and other mathematical and engineering sciences; interaction of mechanics with dynamical systems, advanced materials, control and computation; electromechanics; biomechanics.
Articles include full length papers; topical overviews; brief notes; discussions and comments on published papers; book reviews; and an international calendar of conferences.
Meccanica, the official journal of the Italian Association of Theoretical and Applied Mechanics, was established in 1966.
