Evaluation of Featured Results
This project addresses the design study of flipwing turbine for 1000 W output in 1.5 m/s water flow
to minimize material cost using materials like plastic, aluminum and steel and minimize size of
components with using FEA software and number of vanes for the power generation using CFD
Software. This project is significant in development of demanding clean technology for power
generation. The following methodology was used for the intended progress of the project.
 Approximate Analytical Approach.
 3-D modeling of Flip wing Turbine with different blade size, and number of blade(3
and 4).
 Steps for FEA analysis
 Steps for CFD Analysis
The following future work will be done in Part B of ME 295.
 Flip-wing’s minimization of material cost using materials like plastic, Aluminum and
Steel in FEA software without exceeding 2mm deflection , Von Mises stress .
 Minimization of total mass of components like disk, Center shaft, Pin rode shafts
without exceeding 2mm deflection and von mises stress.
 CFD analysis to check more than 1-1.2 KW power output at turbine shaft of
optimized FEA design by Flow-work simulation software with necessary assumption.
