| Abstract | ||||
| Pump sumps often face issues like water stagnation and vortex formation due to inadequate consideration of hydraulic conditions during design. This research employs Computational Fluid Dynamics (CFD) simulations to explore how different sump shapes and configurations impact flow patterns. Key factors examined include sump geometry, suction direction, inlet level, and the positional relationship between inlet and outlet pipes. The results demonstrate that circular sumps, high-level inlets, and horizontal suction pipes significantly reduce water stagnation and vortex intensity. Placing inlet and suction pipes on opposite sides further improves flow patterns. These findings provide practical guidelines for designing more efficient pump sumps, enhancing hydraulic performance, and reducing maintenance needs. Additionally, the study underscores the importance of optimizing sump configurations for various operational scenarios. By integrating advanced computational techniques with robust design principles, the research offers actionable recommendations that can be directly applied to improve the performance and reliability of pump sumps. The insights gained from CFD simulations pave the way for more efficient water management practices, ultimately contributing to reduced operational costs and enhanced system reliability in hydraulic engineering applications. This study highlights the critical role of detailed hydraulic analysis in pump sump design and demonstrates the value of CFD simulations in developing effective solutions for minimizing common hydraulic issues. | ||||
