Abstract: The present invention relates to a modular vortex-siphon cascade system for micro-hydropower generation under ultra-low head conditions. The system comprises a tangential inlet for inducing rotational flow, a conical vortex chamber for vortex formation, and a turbine runner for energy extraction. An air-trap chamber with primary and secondary air separation regions stabilizes the vortex, while a siphon-assisted discharge unit generates a pressure differential to enhance flow velocity and torque. The system supports a modular cascading configuration for sequential energy extraction and is suitable for decentralized power generation in low-head water bodies The modular design enables multiple units to be connected in series, facilitating continuous energy harvesting from a single low-head resource without extensive infrastructure. Each module operates independently yet contributes cumulatively, making the system highly adaptable for decentralized energy production. Performance evaluations through computational fluid dynamics confirm enhanced velocity profiles, stable vortex formation, and improved energy conversion efficiency under ultra-low head conditions, positioning this invention as a practical solution for sustainable power in resource-constrained settings.
