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.

Results of Flip-wing’s minimization of material cost using materials like plastic,

Aluminum and Steel in FEA software without exceeding 2mm deflection , Von
