Abstract :

One of the main components of various industries are axial pumps, which are often used in the field of marine propellants with nozzles, waterjet systems, agricultural applications, sewage treatment, etc. These pumps are used for low head and high-volume flow. This issue has led to the use of numerical solution methods and the development of these methods to predict and optimize the hydraulic performance of these pumps. In this study, by analysing and simulating the three-dimensional and turbulent flow of the water agent fluid in compressible and unstable conditions and activating the two-phase flow due to the possibility of cavitation phenomenon, the effective factors in increasing or decreasing the hydraulic efficiency and axial pump head such as tip lagging are investigated. Blade, wrap angle, number of blades and the height of the cylindrical area of the blade are investigated and subjected to optimization and sensitivity analysis.
