Increasing Efficiency of Overshot Waterwheel with Overflow Keeper Double Nozzle (OKDN) by using Hydraulic Ram System
Waterwheel has been developed over two millennia to be efficient hydraulic machine but have weaknesses due to his inability to increase the torque although the flow of water has been increased-because the e ffic ie ncy o f this water whee l is only d epe ndent on the volume o fb uckets and gravitational those are always constant.In this study demonstrated a new method to improve the torque of overshot waterwheel (OWW) by recapturing overflow of water from the buckets and the excess flow from the channel to be converted into kinetic energy through the nozzle and then squirt against to the curve vane in the buckets by using hydraulic ram pump system.The result of performance test proved that OKDN using hydraulics ram able to improve their efficiency more than conventional overshot wheel.
