Computational and Experimental Study of a Gas/Steam Turbine ― Derivative Axial Flow Impulse-Type Hydraulic Turbine

Mark D. Villanueva and Jonathan C. Maglasang
Abstract—In large water supply system where the source is elevated, the water reaches its destination with still a lot of energy to spare. This energy can be tapped by installing appropriate hydraulic turbine along the pipeline. A prototype gas/steam turbine-derivative axial flow impulse-type was designed and simulated using the Solid Works flow simulation software. It was then fabricated and tested. The experimental results indicated that at no load condition, the rotational speed ranges from 650 to 850 RPM depending on the water flow rate which ranges from 8.51 to 18.34 l/s. At 381 RPM, the torque was 3.05 N-m and the efficiency was 42%. The maximum efficiency occurred within the 300-350 RPM range. The flow at the exit was not much disturbed demonstrating that its installation did not hamper the supply line. It is recommended that further studies of prototypes designed on the same concept be done.

Index Terms—Axial flow, gas/steam turbine-derivative, hydraulic turbine, impulse-type.
