Abstract
Cavitation in centrifugal pumps is a critical phenomenon that affects pump performance, longevity, and operational reliability. It occurs when the local pressure in the pump falls below the vapor pressure of the liquid, leading to the formation and subsequent collapse of vapor bubbles. This study investigates cavitation characteristics in centrifugal pumps through experimental analysis and numerical simulation, using technologies and methodologies available up to 2020. The research evaluates the effect of inlet pressure, flow rate, and impeller geometry on cavitation inception and intensity. The findings highlight the impact of cavitation on pump efficiency and vibration levels. Recommendations for cavitation mitigation based on design and operational parameters are discussed. This work aims to enhance understanding of cavitation dynamics to improve centrifugal pump design and operational strategies in industrial applications.
