Design and Development of a Hydro-Turbine

Abstract. The usage of fossil fuels is slowly being replaced by cleaner and more renewable sources of energy. Since Michigan has varying amounts of sunlight, the use of solar energy would not be practical. With the Flint River located on the campus of the University of Michigan-Flint, hydroelectric energy may be a feasible alternative. Connecting a micro-turbine to a generator and using the natural current of the river can prospectively generate 200 to 300 watts of energy. Funneling the water 9442

    1. Design and Development of a Hydro-Turbine John Connor Elisia Garcia Som Tantipitham Faculty Advisor: Dr. Quamrul Mazumder

    3. Project Schedule

    4. Progress

    5. Cost Analysis

    6. Efficiency

    7. Force Assume: ?water = 62.4 lbm/ft3 Vwater init = 7.5 mph = 11ft/s Vwater final = 7.0 mph = 10.26 ft/s Propeller Diameter = 292 mm = 0 .958 ft Area of Blade = 90 in2= 0.625 ft2 One dimensional Flow

    8. Detail Drawings

    9. FEA Stress analysis for the turbine support frame Max stress occurs at the fixed ends Max stress of about 16000 Pa

    10. FEA Total deformation of support frame Max deformation occurs where turbine rest Max deformation of about 1.7e-8m

    11. FEA Stress analysis on the turbine 1400N forced placed on shaft Max stress 14357Pa

    12. FEA Total deformation of turbine 1400N force placed on the shaft Max deformations is about 0.17m Cause of large deformations is because sheet metal was used for the blades

    13. Assembly

    14. Assembly

    15. Assembly Ametek 38 Volt Motor Can deliver 300W with 600rpms More compacted and lighter

    16. Ametek 38 Volt Motor

    17. Assembly

    18. Changes from Original Redesigned 10 blades turbine to 8 Reversed placement of generator on the support to better fit the location Changed generators

    19. Difficulties First generator didnt perform as expected Water flow of the river was inconsistent River dried up before final testing could be done

    20. Difficulties

    21. Plan B Testing Using a power washer to simulate water flow Voltage output of 35.5V Using the performance curve, this is equivalent to 398W of power

    22. Completed Generator
