2. Introduction
KAEE 2017
3D modeling is an effective method of teaching engineering concepts and design
Students can learn engineering concepts through testing out the parts they design
Guiding students through designing parts teaches integral software and its programming language
Real-world applications Hydropower!

4. Introduction to hydropower
What is hydropower?
Hydropower generation
Environmental impacts
Examples of hydropower projects
Turbine design principles
Computer lesson
Working in pairs design your own turbine

5. What is hydropower?
Is a form of renewable energy that uses the water stored in dams or flowing rivers to create electricity.
The water is moved through a turbine that spins a generator that converts the mechanical energy into electrical energy.

6. Hydropower Generation
About 13% of the renewable energy in the US comes from hydropower
Of this 6 to 7% is from hydropower.
Most of the hydropower generated in the US is in the Pacific Northwest

7. How it works https://www.youtube.com/watch?v=q8HmRLCgDAI
Utilizes the head (slope) and velocity of water

8. Environmental Impacts
Does not pollute water or the air
Fish migration
Reduced CO2 emissions
Removal of plants and animals
Change is flow regime

9. Types of Hydropower Projects
Impoundments
Most common (2,400 of the 80,000 dams produce power)
Hoover dam
Diversions, aka run-of-the river
Niagara Falls
Pump storage
Silvette, Austria

10. Sizes of hydropower LARGE HYDROPOWER
Although definitions vary, DOE defines large hydropower as facilities that have a capacity of more than 30 megawatts (MW).
SMALL HYDROPOWER
Although definitions vary, DOE defines small hydropower as projects that generate 10 MW or less of power.
MICRO HYDROPOWER
A micro hydropower plant has a capacity of up to 100 kilowatts. A small or micro-hydroelectric power system can produce enough electricity for a home, farm, ranch, or village.

11. Turbine design principles
Forced movement using water density, gravity, and velocity
Pitch
Size
Number of blades
Shape
Scoping of the blades

12. Any questions?

13. 3D SolidWorks
KAEE 2017
3D SolidWorks is software used in most postsecondary engineering programs
Professional and includes many different tools
Has very high precision
Not very intuitive or user-friendly; most would need to be taught by person familiar with software
Fairly expensive; one copy of the Student Edition is $150

14. Computer program lesson Kaplan or propeller design

15. Instructions for Making a Turbine in SolidWorks
