Abstract
This study investigates the relationship between water flow rate and the efficiency of a Cone-Enhanced Split Reaction Turbine (CESRT), which is typically used in pico-hydro systems for low-head hydropower applications. The research uses a Response Surface Methodology (RSM) to analyze the impact of cone size, torque, and bypass angle on turbine performance. The experimental setup simulates a pico-hydro system, allowing for controlled manipulation of flow rate and measurement of turbine performance. A cone-enhanced split reaction turbine is tested with varying cone size heights, and data is collected on torque, flow rate, and speed under different load resistances and bypass angle settings. The results show that cone size significantly impacts volume flow rate, with the 2.25-inch cone providing the most efficient performance. Increasing both torque and bypass angle generally leads to a higher volume flow rate, but the magnitude of this effect varies depending on the cone size. The bypass angle also plays a significant role in the flow dynamics, particularly for larger cone sizes, while torque has minimal impact on volume flow rate across all cone configurations. The optimum volume flow rate and efficiency conditions are achieved at a torque of 60 N-m, a bypass angle of 22.5°, and a 2.25-inch cone turbine type. Under these conditions, the maximum achieved volume flow rate is 79.7799 m³/hr, and the turbine's efficiency is 77.0772%. The study concludes that the RSM model is valid for predicting the volume flow rate of the cone-enhanced split reaction turbine and can be used to optimize its design and operation.
